Hello,
I’m just starting out with CFD/FEA and have a question. I’m attempting to model a heat load that is immersed in dielectric liquid (roughly similar to mineral oil) using a CHT model. When attempting to model with the dielectric, I do not seen a great amount of convective flow. I did a sanity test with water as my fluid and I see a reasonable flow, which brings me to my question.
The default parameters for water in SimScale list the equation of state as rhoConst. After looking through the documentation, rhoConst means that the density of the liquid is fixed, however we know that natural convection is due to a change in density/bouyancy from heating.
How is simscale able to simulate convection when a material’s equation of state is set to rhoConst? What am I missing? Thanks!
