Consider the following stencil. For steady two-dimensional convection-diffusion problem, if the general discretized equation is aP φP=aW φW+aE φE+aS φS+aN φN, what is aN using the hybrid differencing scheme?(Note: ϕ, a, F and D are the flow variable, coefficients, convective mass flux per unit area and diffusion conductance respectively). |
