Hello CFD-Community,


I simulate a microfluidics device in which the fluid is periodically heated and cooled and I am interested in the heating power density [W/m²] at a surface of 0.5mm².



Since it is a fluid-solid interface, I try:

areaInt(Wall Heat Flux)@surface = 0,00002 W --> 40 W/m²
areaInt(HeatFlux)@surface = nothing
areaAve(Wall Heat Flux)@surface = 2000 W/m²
area Ave(Heat Flux)@surface 0,000025 W/m²

I am confused which result is the correct one?

Thanks Kauf
