This tutorial shows how to set up a numerical model with conjugated heat transfer including radiation modeling using the chtMultiRegionFoam solver. The case configuration is a light bulb of 60 W power simulated transiently with free convection. Radiation is modeled using the fvDom model of OpenFOAM®. The tutorial uses many advanced features of OpenFOAM® to efficiently simulate an industrial heat transfer application:
- chtMultiRegionFoam with 3 domains (1 fluid and 2 solids), transient and turbulent flow, perfect gas.
- snappyHexMesh in multi-regions framework with boundary layer insertion.
- radiation modeling with fvDom.
- Argon free convection modeling.
- source term for heat generation in the filament.
- python script for plotting temperature probes in the argon domain.
- Around 1 hours on 4 cores – AMD® Ryzen 5 4600h.
OpenFOAM®: Tested on versions 2006+.
- The tutorial is designed to run on 4 cores but can be easily modified to be run on the number of core chosen by the user.
- Paraview (post-processing).
