Question

An optimal prediction is ______________

(a) Computational only

(b) A combination of Computational and Experimental

(c) Analytical only

(d) Experimental only

I had been asked this question in a national level competition.

I would like to ask this question from CFD Advantages and Disadvantages in portion Philosophy of Computational Fluid Dynamics of Computational Fluid Dynamics

Answer 1

Right option is (b) A combination of Computational and Experimental

For explanation I would say: Experimental results are difficult to obtain in all the places, especially, in the locations of mounting. If we solely rely upon CFD, problem may arise out of wrong modelling. So, it is always better to use CFD models to get detailed results and using experiments to validate them.
