Students in MAE 6510 will need to select the surface heat transfer coefficient Surface Heat Transfer Coefficient (NOT the Surface Nusselt Number) in addition to the skin friction coefficient Skin Friction Coefficient for your HW assignment, in order to calculate the local Nusselt number. Reference values used are length and temperature. Hence, you You will need to specify the appropriate reference density, velocity, length, and temperature in FLUENT before you export the skin friction coefficient and heat transfer coefficient into the post-processor. One can use the heat transfer coefficient to then calculate the local Nusselt number in post-processing. If you select to export the Surface Nusselt Number directly from Data File Quantities, you will be exporting a Nusselt Number that is calculated at one x value only (the reference length of 1m in our case). It is always good practice to look up how ANSYS calculates quantities like these each time you choose to export.
