Question:
Carbon dioxide and hydrogen as ideal gases at 1 atm and −20°C flow in parallel over a flat plate. The flow velocity of each gas is 1 m/s and the surface temperature of the 3-m-long plate is maintained at 20°C. Using an appropriate software, evaluate the local Reynolds number, the local Nusselt number, and the local convection heat transfer coefficient along the plate for each gas. By varying the location along the plate for 0.2 ≤ x ≤ 3 m, plot the local Reynolds number, the local Nusselt number, and the local convection heat transfer coefficient for each gas as functions of x. Discuss which gas has higher local Nusselt number and which gas has higher convection heat transfer coefficient along the plate. Assume flow is laminar but make sure to verify this assumption.
