teejey is on a distinguished road
I'm trying to model the flow inside a flat heat pipe,with water as working fluid, which consists of vapour core, a wick structure and an outer casing. initially i tried to model the flow inside vapour core and wick structure separately, but couldnt get the proper fluid distribution. the error was with specifying the pressure at the boundaries.
As am new to FLUENT, i couldnt develop the problem correctly for formulating the wick structure.
can anyone help me regarding how to specify the pressure @ boundaries for the vapour core alone and how to develop the problem in porous media..i tried reading the tutorial for porous media but was not able to obtain a correct picture.
hope to hear from you soon.
Thanks in advance
