Computational Fluid Dynamics Mcqs

Q:

Which among the following is a reason why we do not completely rely upon ground tests for analysing fluid dynamics?

A) Three-dimensional flows cannot be analysed B) Facilities do not exist in all fight regimes
C) The output generated is not as accurate as theoretical analysis D) Long run-time
 
Answer & Explanation Answer: B) Facilities do not exist in all fight regimes

Explanation: Ground test facilities can be used to model three-dimensional flows also and even they produce accurate results in a less run-time. But they cannot be used to test all flight regimes as they want artificial set-up for every single property of the flow.
