Questionsir can u just give a brief introduction about research tool
AnswerComputational Fluid Dynamics (CFD) is the name given to methods or techniques used to simulate fluid behavior by solving the mathematical equations that describe fluid motion. Basically the equations are solved at a finite number of points (locations) surrounding a body... Evaluation of certain terms in the equations link all the points together (i.e. you solve for the field as a whole). At each of these points you will calculate fluid properties such as velocity, pressure, density, temperature... For complex shapes (complete cars, airplanes, ships, ...) There can be millions of points and hence millions of equations thus only large clusters of computers are used for these very complex problems. Smaller problems such as a wing or airfoil can be solved on a PC. The solution data is then graphically depicted in shaded pictures indicating the pressure or velocity (field) surrounding the object analyzed.
Hope this gives you an idea of what CFD is about,
