Hi,
Actually, I am trying to calculate friction factor for flows in rectangular sinusoidal mini-channel, while the height, width length are .250, 1 and 1 mm respectively, I also tried to model the mesh by following a published research paper, the developed mesh sizes where 1million to 4 million cells. But still, the results were far away from the theoretical and experimental values. like the expected friction value was expected around 0.2 but the values I got were more than 1. For the analysis, I considered the viscous laminar model with velocity inlet and press outlet were B. conditions. while the considered Re number is 100, so am I supposed to use any other CFD model? or the problem is with the mesh? Thanks in advance |
