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

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

ABSTRACT
The overall goal of the work presented in this thesis is to extend the physical understanding of the external aerodynamics associated with the rotating case of Hovering Rotor using Computational Fluid Dynamics (CFD) technique.
Rotating blades encounter tip vortices coming from preceding blades, which results in Blade Vortex Interaction(BVI) responsible for producing dynamic effects. Understanding the complex flow field due to this dynamic effects produced by wakes is therefore very important for the prediction of effects such as blad ....etc

INTRODUCTION
The abbreviation CFD stands for computational fluid dynamics. It represents a vast area of numerical analysis in the field of fluidâ„¢s flow phenomena. Headway in the field of CFD simulations is strongly dependent on the development of computer-related technologies and on the advancement of our understanding and solving ordinary and partial differential equations (ODE and PDE). However CFD is much more than just computer and numerical science. Since direct numerical solving of complex flows in real-like conditions requires ....etc
