compressible flow with heat transfer

I am attempting to model hydrogen flowing through a heat exchanger at high speeds and temps (250m/s and 2000K). In order to do this, the change in density of the hydrogen must be taken into account as...

Inconsistent uni-directional constraint with Conjugate Heat transfer

I am trying to model a simple high temperature hydrogen heat exchanger with the conjugate heat transfer module. While I have been sucessfull in modeling individual tubes of the hydrogen alone, I cannot...

Fluid across cylinder with heat source

Hi! I am doing a small project about an heat exchanger. First I should study the Reynolds number effect and the vortex shedding. I already have some results about that (I should be able to calculate...

Laminar Counter-flow in Concentric Pipes

Hello. I'm relatively new to COMSOL and I've been trying to model a simple counter-flow through concentric double-pipes. Currently, I have the model in a 2-D axisymmetric configuration and three...
