Hello every one
I am beginer of COMSOL user and now trying to simulate free convection in Porous media. Specifically, I'm trying to see the vertical groundwater flux induced by termal effect of nuclear waste. There are previous studies, although it is very slow, showing the flux due to thermal expansion and buoyancy convection. The problem is I want to use Darcy law to describe the fluid motion (in porous media) but It seem's that in this module, fluid density(in porous media) does not change by temperature. It will be thankful if you suggests some direction for me.
