Aerodynamics, a subset of fluid dynamics, is the study of the behavior of objects when exposed to air. Hydrodynamics, another subset of fluid dynamics, is very similar to aerodynamics and has similar laws. However, hydrodynamics shows the behavior of liquids instead of gasses. Reynolds Numbers, created by British scientist and engineer Osborne Reynolds, describe the way fluids behave against objects. Bernoulli’s principle, discovered by Daniel Bernoulli, states that faster fluid flow creates lower pressure

B) Provide the main aim of the article, as concisely and clearly as possible. Prove, through the use of computational fluid dynamics (CFD) simulations that the front wing is a vital component because it is where air first meets the car. It improves aerodynamic performance more than other add on devices like roof spoiler, nose wing and bargeboard. C) Provide at least one diagram that best illustrates the mathematical model. D) Give the main equations (1-3 equations) at a level of your understanding

While there is certainly much left to be explained and understood in the field of fluid dynamics, there is still a certain level of common sense that one has concerning what one would consider to be “ordinary” fluids, such as water. It makes sense that such fluids, say, take the shape of their containers, or tend to flow down an inclined plane, or proceed with the same mass flow rate given that the fluid does not build up along the flow channel. Likewise, with solids, there are certain, seemingly

Just as Computational Fluid Dynamics (CFD) is a central tool in the development of advanced design across all industries, multiphase-CFD (M-CFD) is sought after to support the escalation of performance, efficiency and reliability in a widespread range of applications that rely on boiling heat transfer: from microelectronics, to combustion engine cooling, and further to highly specialized design and licensing of nuclear reactor fuel. Due to the markedly complex physics involved, the application of

1. Conductive arteries – Conductive arteries are the most proximal compartment of the coronary arterial system. Their diameter is generally ranging from 500 μm up to 2-5 mm. These are large epicardial coronary arteries that work as a capacitance function for the blood flow. They have very low resistance to blood flow and therefore, the pressure drop along the length of conductive arteries is negligible. The conductive arteries have an inbuilt characteristic of maintaining the shear stress by changing

THE FOUNDER OF MODERN FLUID DYNAMICS: LUDWIG PRANTDL A fluid is defined as a substance that does not have any determined shape and is deformed continuously by a shear force, thus it can be said that fluid mechanics is considered as a part of physics which is concerning about gases, liquids and plasmas, in the other words, no solid phases.[1] Modern fluid mechanics is based on Continuum Hypothesis. This hypothesis assumes that a matter is continuous, hence while a matter is examined, atomic structure

Procedure Experimental set-up The Bernoulli’s theorem apparatus is set up on the hydraulic bench so that its base is horizontal for accurate height measurements from the manometer. The rig outflow tube is positioned above the volumetric tank. The rig inlet is then connected to the bench flow supply followed by closing the bench and the apparatus flow control valve. The pump is then started. The bench valve is gradually opened to fill the test rig with water. The bench valve and rig flow

Current spirometers available in the market are expensive and usually

In recent times, CFD analysis, with the advent of computer architectures with superfast processing capabilities are rapidly emerging as an alternative to wind tunnel tests. In vehicles body development, reducing of drag is essential for improving fuel consumption as well as protect the global environment and the aerodynamics refined body is also aesthetically attractive, it will appeal to the customers. In this papers the process taken to optimize the shape of a vehicles . The Autodesk CFD program
