Thermal CFD and Stress Analysis of an Exhaust Manifold
ADINA is a unique tool to perform coupled CFD and structural analyses, and we are strengthening the program continuously for such applications. Here we focus on the analysis of a manifold and consider
A particular capability needed here, with the meshes used, is the automatic coupling of the temperature between totally different meshes.
The figures below show the model of the fluid and solid, and some temperature and stress results. The movie above shows some velocity results in the outlet. The model contains a total of about 5 million elements. For the fluid the k-omega turbulence model is used. The Re, Pe and Pr numbers are
Re = 0.74 x 105, Pe = 0.54 x 105, Pr = 0.73.
This model was solved with ADINA, version 8.5, because we have implemented some significant computational improvements that are used in this solution.
