Heatsink - OpenFOAM

Authors:  Juris Vencels, Valters Dzelme

In this project, an air-cooled parallel plate fin heat sink is modelled using the conjugate heat transfer (CHT) model and heat transfer problem is solved for solid and gas phases. Thermal resistance of the heatsink is estimated in three ways - via the CHT model, analytically and using a simplified FEM model that prescribes an empirical convective heat transfer coefficient on solid-fluid boundaries.

This project is part of the EOF-Library training course. EOF-Library is efficient, fully parallelized Elmer FEM and OpenFOAM coupler designed for coupled electromagnetic, fluid and heat transfer simulations.
