as shown in picture case is jet impingement. i want to calculate the nusselt number at a stagnation point. case is unsteady transient heat transfer.
fluent gives abrupt results by using report type > wall fluxes> surface nusselt number. one thing here i need to calculate nusselt number at a single point ( at stagnation) and in wall fluxes > surface nusselt number (surface written) is it ok for point to use surface.
please help how to calculate it.
