can anyone tell me the steps to calculate nusselt number in fluent. case is jet impingement, transient case, plate at constant temperature of 900K air jet at 300k. how to find nusselt number at stagnation number, i calculated the nusselt number but it gives me wrong values from higher values to lower but in figure as shown it should be start from lower value to higher. tried every thing but not getting how to do that.
by wall fluxes >total surface heat flux and then find h and then Nusselt
by wall func heat transfer coef and then nusselt number
by surface heat transfer coeff and nusselt number
by direct finding surface nusselt number
can anyone here help me how to find it what is the right way.
