1.	CFD analyses Fluid Dynamics using this method.(a) Analytical(b) Physical(c) Numerical(d) ExperimentalThe question was posed to me in an international level competition.This interesting question is from Philosophy in division Philosophy of Computational Fluid Dynamics of Computational Fluid Dynamics
Answer» Correct answer is (C) Numerical Easy explanation: As the experimental analysis of fluid flow problems are very expensive, CFD uses theoretical method to analyse them. Among the two theoretical METHODS stated above (ANALYTICAL and Numerical), the analytical method uses approximations which makes the theory UNRELIABLE. So, CFD uses the numerical method.
