Today I thought about the fluid mechanics used in applying lotion. When you squeeze the container to get lotion out, you are actually applying a pressure force to the container. In addition, once the container is set upright, the lotion slowly slips down the side of the container. Since the lotion is coming into contact with the sides of the container shear forces are present. This situation is representative of Couette flow.


Today I thought about how beautiful a flag looks when it waves. I realized that the the wind blowing on the flag actually produces a drag force on the flag. This force acts on both sides of the flag. This drag is due to the wind blowing over the side of the flag. Thus the force itself is actually the shear force acting on the flag. So the next time you see a flag waving, think about the fluid mechanics involved!!!!

When I went for a general health check up I was talking to some nurses about how the blood pressure meter works. I was thrilled by all the fluid mechanics involved! To begin with, the cuff is pumped with air by use of a hand pump. Clearly there are frictional losses in this method. Once the cuff is full of air, it cuts off the blood circulation in the artery, which causes the pressure to build up. The top number in your blood pressure measurement tells you the pressure of your blood when the artery is not pumping blood, and the bottom number tells you the pressure of your blood when blood flow continues. The flow of blood through your veins is much like that of a fluid flowing through a pipe. The flow of blood is steady and laminar, so the velocity profile would be parabolic due to friction occurring at the walls of the arteries. This velocity profile would be altered if there is plaque build up in the artery.


The above scenario of wind flowing through a room describes a rudimentary wind tunnel. A wind tunnel is a chamber built for the purpose of examining the characteristics of airflow in contact with solid objects, such as aircraft and automobiles. The wind tunnel represents a safe and judicious use of the properties of fluid mechanics. Its purpose is to test the interaction of airflow and solids in relative motion: in other words, either the aircraft has to be moving against the airflow, as it does in flight, or the airflow can be moving against a stationary aircraft. The first of these choices, of course, poses a number of dangers; on the other hand, there is little danger in exposing a stationary craft to winds at speeds simulating that of the aircraft in flight.


Though applications of Bernoulli's principle are among the most dramatic examples of fluid mechanics in operation, the everyday world is filled with instances of other ideas at work. Pascal's principle, for instance, can be seen in the operation of any number of machines that represent variations on the idea of a hydraulic press. Among these is the hydraulic jack used to raise a car off the floor of an auto mechanic's shop.


The turbine was developed in the mid-eighteenth century, and later it was applied to the extraction of power from hydroelectric dams, the first of which was constructed in 1894. Today, hydroelectric dams provide electric power to millions of homes around the world. Among the most dramatic examples of fluid mechanics in action, hydroelectric dams are vast in size and equally impressive in the power they can generate using a completely renewable resource: water.


Fluid mechanics is a discipline of physics that studies fluids (liquids, gases, and plasmas), as well as the forces that act on them. Fluid statics, or the study of fluids at rest, and fluid dynamics, or the study of the effect of forces on fluid motion, are the two branches of fluid mechanics. It is a branch of continuum mechanics that models matter without taking into account the fact that it is made up of atoms, that is, it models matter from a macroscopic rather than microscopic perspective. Fluid mechanics, particularly fluid dynamics, is a burgeoning field of study with numerous unsolved or partially solved issues. Fluid mechanics is a mathematically challenging subject that is best tackled using numerical methods, most commonly computers.


Fluid dynamics is a branch of fluid mechanics that studies the flow of fluids in motion. In the generally recognised fluid mechanics, there are various fields of fluid dynamics, aerodynamics, and hydrodynamics. Calculating force and moments, measuring the mass flow rate of oil through pipelines, anticipating weather patterns, analysing interstellar nebulae, and modelling are all examples of this. Fluid dynamics is studied by scientists from several fields. Planetary evolution, ocean tides, weather patterns, plate tectonics, and blood circulation are all studied using fluid dynamics. Rocket engines, wind turbines, oil pipelines, and air conditioning systems are just a few of the key technological uses of fluid dynamics.


Fluid mechanics is a dynamic research field in science and engineering, with many unsolved or partially solved problems. Fluid dynamics is a mathematically challenging subject. Numerical approaches, usually involving computers, are sometimes the best way to tackle problems. Fluid mechanics is a subject that is particularly amenable to cross-fertilization with other sciences and engineering disciplines since fluids have the potential to transfer matter and its properties as well as transmit force. Fluid mechanics is important in many fields of engineering, including mechanical, chemical, petrochemical, civil, metallurgical, biological, and ecological. The continuity assumption is an idealisation of continuum mechanics that allows fluids to be viewed as continuous even if they are made up of molecules on a tiny scale. Fluid statics or hydrostatics is the branch of fluid mechanics that studies fluids at rest. It embraces the study of the conditions under which fluids are at rest in stable equilibrium; and is contrasted with fluid dynamics, the study of fluids in motion. Hydrostatics offers physical explanations for many phenomena of everyday life, such as why atmospheric pressure changes with altitude, why wood and oil float on water, and why the surface of water is always level whatever the shape of its container [1-5].






Machine learning has connected with many other displines or research directions, for example it has been combined with materials, fluid mechanics and so many research directions, so what is your daily life if you have to use machine learning methods to complete your PhD topic or your postdoc research?


For example, you can give me a schedule or proportion or your daily life, for example, you have to use half of your workday to decode the ML literatures or algorithms and program, debug, run and test this model, and the other half to do experiments.


Understanding how fluids move can help us get to grips with how a virus like the one causing COVID-19 travels from an infected person to others. This is because when we cough or sneeze we expel micro-droplets whose motion is governed by the principles of fluid mechanics. Understanding the way the virus is transmitted can inform public health interventions to minimise the risk.


Recent studies have shown that our current understanding of the routes of transmission of respiratory diseases is limited and based on an oversimplified model. Recent developments in fluid mechanics and epidemiology have shown that turbulent puffs, emitted by sneezing or coughing, transport pathogens much further than expected.


Fluid mechanics is a field of physics that studies the behavior of fluids (liquids, gases, and plasmas) at rest or in motion. It is a subject without the information that it is made out of atoms; that is, it models matter from a macroscopic viewpoint.A fluid is a substance that can be continuously deformed and has a finite resistance to deformation. Depending on its properties, we can distinguish the following types of fluids:Compressible and incompressible fluids


Newtonian and non-Newtonian fluidsIdeal and real fluids.A wide range of fluid mechanics problems is solved by mathematical equations such as the continuity equation or Archimedes' principle describing fluids' behavior. These equations are derived from the fundamental laws of physics, such as the law of conservation of mass, momentum, and the law of conservation of momentum.


From a mechanical engineering point of view, calculations to study the motion of fluid particles are sometimes combined with numerical calculation techniques. The result is what is known as computational fluid dynamics.In this article, we describe some fluid mechanics application examples to show the importance of fluids in mechanical and chemical engineering in our daily lives.Example 1: Circulatory SystemBlood is an example of fluid particles that move through the interior of our body. Likewise, the circulatory system is an example of fluid mechanics in which the concepts of pressure and density are essential for proper functioning.


The regulation of pressure and water flow in an irrigation system is another example of the application of fluid mechanics. Fluid mechanics is used to calculating the flow rate and pressure required to move water through the system.In most sprinkler designs the oscillating motion is dependent on the water pressure. Therefore, flow and pressure are also crucial elements in defining the reach of the water.


The optimal aerodynamics of a windmill used in a wind power installation is studied using fluid mechanics. Air is a fluid in motion that, depending on how the impact is made with the blades of the wind turbine, varies the performance and obtaining the electrical energy generated.


This action causes the blades to rotate, which produces mechanical energy.The study of the differential equations of a fluid allows the design of more efficient turbines and suitable circuits to withstand these pressure and temperature conditions.Example 7: A Hydroelectric PlantA hydraulic power plant is a civil engineering work in which water is stored to drive a set of turbines and generate electricity. In this fluid mechanics example, we can study both fluid flow and fluids at rest.The physical study of fluid statics is necessary to calculate the dimensioning of the water dam to resist the water pressure. On the other hand, to calculate the sizing and performance of hydraulic turbines, we must take into account the equations that regulate moving fluids, such as the Bernoulli equation or the Navier-Stokes equations.Example 8: Formula 1 Race CarsAnother example of fluid mechanics is in the design of vehicles, such as cars and motorbikes.
