Dear Mr./Miss.,
We manufactured a liquid cooled heat sink by 3DP, and we intend to experimentally and numerically study the thermal and flow performances of the heat sink. The problem is that the roughness of cooling channel surface is not perfectly smooth due to the uncertainty during 3DP process. Therefore, is it possible to use any boundary condition setup to simulate such kind of rough surface in CFD simulation?
Kind regards, Hao LI
