fidu is on a distinguished road
Hi all I would like to model the particle dispersion of a thermal runaway battery. The idea is to create a simple model that should be able to simulate particle dispersion of various sizes (0.01-0.1, 0.1-0.45, 0.45-1, 1-1.6) in millimeters corresponding to various concentrations (the overall volume fraction should be lower than 10%). These particles are dispersed rather fast together with a gas mixture of known composition in my geometry. My goal is then to analyze how geometric changes affect the particle distribution in the geometry.... For this purpose, I aim to create a physical model that is as simple as possible with low computational cost, yet still provides realistic results.
So currently I planning to implement Lagrangian Multiphase Model with RANS using k-epsilon. Is that the appropriate approach or would you rather recommend the Discrete Element model or even the Eulerian Multiphase model?
