Pressure
Wind – what causes it?, cont.
Pressure differences cause the flow of fluids (gases and liquids)
pressure is always measured relative to some reference pressure
Sometimes relative to vacuum  absolute
Sometimes relative to atmospheric pressure

Numerical Simulation for Aerodynamic Characteristics of Low Altitude and Subsonic Flight Vehicle
Abstract—In order to analyze the drag characteristics of the vehicle having different war head and empennage, the computational fluid dynamics numerical simulation was used. The method was based on fully hexahedral mesh and three-dimensional Navier-Stokes equations and Spalart-Allmaras turbulence model. Through numerical simulation the flow field structures and computational aerodynamic characteristics were obtained. T ....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

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

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

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
