Question

In the over-relaxed approach, the importance of the term involving ΦF and ΦC _________ as the non-orthogonality _________

(a) decreases, increases

(b) remains the same, increases

(c) increases, remains the same

(d) increases, increases

This question was posed to me in an internship interview.

My question is based upon Diffusion Problem topic in division Diffusion Problem of Computational Fluid Dynamics

Answer 1

Right option is (d) increases, increases

The explanation: The importance of the term involving ΦF and ΦC decreases when the non-orthogonality decreases for the minimum correction approach. For the over-relaxed approach, the importance increases.
