Q) Consider a CFD simulation for a two-dimensional laminar flow between two parallel plates. The computational domain can be considered as a 2D rectangular channel with dimensions of height H = 0.1 m and length L= 1 m. The working fluid can be taken as air at room temperature. The numerical solutions can be verified by comparing against the analytical solution for the horizontal velocity u in the fully developed region and the results are tabulated in Table 1 and Table 2.
