Students in MAE 6510 will need to select the Nusselt number heat transfer coefficient, h, in addition to the skin friction coefficient for your HW assignment. For the , in order to calculate the local Nusselt number, reference . Reference values used are length and temperature. Hence, you will need to specify the appropriate reference density, velocity, length, and temperature in FLUENT before you export the skin friction coefficient and Nusselt number 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 (x = 1m). It is always good practice to look up how ANSYS calculates quantities like these each time you choose to export.
