Why should you use CFD when we know empirical and semi-empirical models have worked before? correct answer: Because it is with CFD possible to model new equipment which has not yet been tested. Thus one can simulate performance of the equipment before spending tons of money to test in reality. W...

Typical shapes of unstructured grid cells used in 2D grids are quadrilateral and ______________________ correct answer: triangular a grid is ___________ if any line connecting centers of neighboring cells face between the cells correct answer: orthogonal one disadvantage of using unstructure...

What is CFD? How does CFD work? correct answer: computational fluid dynamics: a set of numerical methods applied to obtain approximate solutions of problems of fluid dynamics and heat transfer. How it Works: - The flow is broken down (discretized) into elements that make up the mesh of the flu...

"CFD" stands for correct answer: Computational Fluid Dynamics CFD and Computational Aerodynamics are different names for the same thing correct answer: False The four primary steps in the CFD process are (in order) correct answer: geometry modeling, grid generation, flow solution, post pr...

Pros and Cons of Experimental correct answer: Pros: -Realistic results for flight conditions in tunnel -Good for finding trends and correlating variables Cons: -Unable to match all real flight conditions (e.g. Mach and Reynolds) -Costly (equipment, manufacturing time) -tunnel corrections ...
