nusselt number
 
Dear all How do i compute and plot local nusselt number in flow direction in a rectangular channel? flow direction:z and other direction:x,y plot of nusselt along of channel(z) give several plots. Nu(z)=1/Tbalk(z)*(dTbalk/dX) please guide me Best regard Avesta

Hi,

I had the same problem for other quantities. I didn't manage with FLUENT. I exported the data, and by the use of a code written in MATLAB, I provided the extraction of the data of interest. Maybe is not the best solution but could be a way...
