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

Gud morning sir/ma
I am a undergraduate student, I was given a project to work to repair an old subsonic wind tunnel made by plint and partner company in 31 years ago. So I find it veri diffucult to get a material online so dat I will b able to get it set up.
I wll b glad if I can get an handbook for the tunnel. So as to get it setup.thank you ....etc

ABSTRACT
For centuries now, wind tunnels have been a key element in scientific research in a number of fields. Experimenting with racecars, airplanes, weather patterns, birds, and various other areas has been made much easier because of its development. In the racing field, for example, the information gathered from this testing can mean the difference between winning and losing a race. Weather simulations can also provide valuable information regarding building stability and safety. This has become very important wh ....etc

ENHANCED PERFORMANCE OF A DOUBLY FED
WIND-POWER INDUCTION GENERATOR AT WIND-
RANGE BOUNDARIES
ABSTRACT
The doubly fed induction generator (DFIG) is one of the largest generators used
with MW-class wind turbines. This paper focuses on the weak performance areas
of grid-connected DFIG-based wind turbines. Basically, the DFIG performance at
low wind speeds, close to the cut in speed, and around the full rating operation (in
the vicinity of rated wind speed) is investigated. For low wind speed region, the
c ....etc

Wind tunnel is a device used to test aero models, automobiles and building structures. It is used to give appropriate shape to the structure. We calculated aerodynamic characteristics analytically for different models whereas wind tunnel can give practical values and we wanted to know how this can be designed ....etc
