COMSOL Multiphysics was used to simulate the heat flux from battery cells via conjugate heat transfer physics which consist of laminar flow and heat transfer in solids and fluids. Laminar flow function was used to simulate natural convection of air within the sealed enclosure. Heat ... Per saperne di più
This case study explains the work we undertook where we modelled an Induction heating system in COMSOL Multiphysics simulation software to correlate the simulation results with actual measurements. The simulated results were cross checked with several different measurement scenarios, ... Per saperne di più
