What is the equivalent of (ρC ΦC)^t+Δt/2 using the second-order upwind Euler scheme for finite volume approach?
(a) \(\frac{3}{2}\) (ρC ΦC)^t+(ρC ΦC)^t-Δt
(b) (ρC ΦC)^t+\(\frac{1}{2}\) (ρC ΦC)^t-Δt
(c) \(\frac{3}{2}\) (ρC ΦC)^t+\(\frac{1}{2}\) (ρC ΦC)^t-Δ t
(d) \(\frac{1}{2}\)(ρC ΦC)^t+\(\frac{1}{2}\) (ρC ΦC)^t-Δ t
I have been asked this question by my college director while I was bunking the class.
My question is taken from Transient Flows topic in portion Transient Flows of Computational Fluid Dynamics
