Hello
Which solver to use for the problem of heat transfer from a solid to a liquid, if the coefficients of thermal conductivity and heat transfer are known? Could be use for this task laplacianFoam? How to set the boundary condition of the third kind (Robin boundary condition)? |

Hello, welcome forum
1- laplacian is not suitable, it solves only transport equation for conjugate heat transfer chtMultiRegionFoam or chtMultiRegionSimpleFoam, can be used 2-a bunch of BC, can be implemented by groovyBC so i suggest first search in forum, there are alot of information here or in wiki, then if you could not reach any conclusion, ask your question

Thanks for your answer! Unfortunately, I can not understand chtMultiRegionFoam yet. But I have an idea how to use laplacianFoam in this task. Necessary to extrude the faces with three kinds of boundary conditions in a finite volume by the length (lambda / alfa), where lambda - the thermal conductivity of solid, alfa - heat transfer coefficient. Extruded faces to set the temperature of the liquid. On the lateral faces set zerogradient. I'll try to write a script to modify the mesh.
