Question

Why ideal conditions should be simulated in CFD?

(a) Experimental analysis is impossible for ideal conditions

(b) Experimental set-up will have imperfections

(c) Experimental set-up will lead to wrong solutions

(d) Experimental analysis can be done for ideal cases

This question was addressed to me by my college director while I was bunking the class.

Asked question is from CFD Advantages and Disadvantages in section Philosophy of Computational Fluid Dynamics of Computational Fluid Dynamics

Answer 1

Right answer is (b) Experimental set-up will have imperfections

To elaborate: Some research purposes will need non-practical processes to be analysed. Setting up experimental analysis for such cases involves a lot of steps and that may not yield proper results as the set-up cannot be perfect.
