Relative roles of CFD and wind tunnel testing in the development of aircraft

Introduction
CFD
CFD is computational technology that enables us to study the dynamics of things that flow.
Using CFD, a computational model that represents a system or device that we want to study is built. Then we apply the fluid flow physics to this virtual prototype, and the software outputs a prediction of the fluid dynamics.

Application
fluid flow, heat transfer , mass , phase change , chemical re ....etc

Computational Fluid Dynamics (CFD) is an extremely effective tool to solve problems involving mass and even heat transfer. Problems with varying degrees of complexities can now be easily solved with the help of appropriately written CFD codes. A CFD analysis is performed to:1)understand the nature of fluid flow around differsnt geometries like an aerofoil or any other shape for that matter.2)find the lift and drag effects for an aerodynamic structure.3)analyse the heat transfer by fluids in devices ranging from radiators to furnaces to gas turb ....etc

ABSTRACT
Since two-three decades, hydrogen has been identified as a versatile potential fuel competent to the conventional fuel such as gasoline. In order to implement it fully and to develop the combustion based power devices which may supply much higher energy density than others, the understanding of hydrogen air combustion mechanism is very essential. In this seminars, Computational Fluid Dynamics (CFD) based numerical simulations have been performed to study the combustion of non-premixed hydrogen- ....etc
