no current magnetic magnet force term in N-S body force in COMSOL

7363 · December 17, 2019, 17:47

Hi
i want to simulate ferrofluid two phase fluid, i use COMSOL for simulation and use two phase flow - laminar flow and no current magnet.
i must to put body force in N-S ?
is this enough?

Hello,

that is going to be amazing. Well, there were two options in order to simulate the ferrofluids. one can be used is the particle motion or tracing to simulate the magnetic particles in the fluid which is not difficult. another option is using the mixture model in comsol. However, you should add body force in both options.

is there any difference between using two phase flow model or mixture?

Well, both the mixture model and particle tracing is kind of two-phase flow. We have different models for different mixtures such as fluid-fluid or fluid-gas, fluid-solid, and fluid-structure interaction is a kind of solid-fluid two-phase flow.
