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
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

1. Abstract
Biogas is a clean environment friendly fuel. Raw biogas contains about 55–65% methane (CH4), 30–45% carbon dioxide (CO2), traces of hydrogen sulfide (H2S) and fractions of water vapors. Presently, it can be used only at the place where it is produced. There is a great need to make biogas transportable. This can be done by compressing the gas in cylinders which is possible only after removing its CO2, H2S and water vapor components. Pilot level trials to compress the biogas have been carried ....etc

Abstract
The purpose of this paper is to investigate using a numerical simulation (computational fluid dynamics or CFD) the effect of the air supply location on the design and performance of the displacement ventilation (DV) system. The results are reported in terms of thermal comfort and indoor air quality. The study focuses on a typical enclosure in CBIT under local thermal and boundary conditions. This includes several pollutants typically found such as carbon-dioxide and volatile organic compounds (VOCs) were inv ....etc

Biogas Generation and its Utililities



.Typically 55% methane (CH4)45% carbon dioxide (CO2)H2S and H2O and trace gases
.Energy comes from methane only
.Energy value of methane 37.78MJ/Nm3
.Energy value of biogas 21MJ/Nm3

Anaerobic digestion technology 

In the absence of dissolved oxygen, anaerobic microorganisms will tend to ferment biodegradable matter to carbon dioxide and methane which can be collected and use as a fuel. This process is called ....etc
