The general discretised form of the transient term using the finite volume approach isFluxT=FluxC C+FluxC C +FluxV. |
| A. | nThe superscript o indicates the older time step. If the Crank-Nicolson method is used with non-uniform grids, what is FluxV? |
| B. | (- frac{ Delta t^{oo}}{ Delta t^o} frac{ rho_c^{oo} V_C phi_c^{oo}}{ Delta t} ) |
| C. | ( frac{ Delta t^{oo}}{ Delta t^o+ Delta t^{oo}} frac{ rho_c^{oo} V_C phi_c^{oo}}{ Delta t} ) |
| D. | (- frac{ Delta t^{oo}}{ Delta t^o+ Delta t^{oo}} frac{ rho_c^{oo} V_C phi_c^{oo}}{ Delta t} ) |
