The value of the flow variable at face centre (Φf) in terms of the flow variable at the owner cell’s centre (ΦC) and the neighbouring cell’s centre (Φf) as given by the face-based stencil is ________
(Note: g is the weighted average)
(a) Φf=gC ΦC+gC Φf
(b) Φf=gC ΦC+gf Φf
(c) Φf=gC ΦC+(1-gC)Φf
(d) Φf=gC ΦC+(1+gC)Φf
I have been asked this question by my college professor while I was bunking the class.
My enquiry is from Diffusion Problem topic in portion Diffusion Problem of Computational Fluid Dynamics
