need to calculate Nusselt Number
need help calculate Nu on blockage
a laminar flow in rectangular pipe
i uploaded the pic of the geometry
blockage has fixed temp 350 K
fluid is air with 300 K temp
thanx for help...
In cases like this, I create a region (plane, line) near the wall (with a distance dx), then the expression dT/dx can be estimated, and therefore the nusselt number. Otherwise, you can use the variable "wall heat coefficient"
I hope this help you, good luck.
