Method how to use 3D results of heat transfer from few operating points for the improvement of models and parameter adjustment in 1D thermodynamic cycle simulations

In the past the methods for generating metal temperature predictions for new engine designs was a considerably time consuming part of all CAE investigations. Within the framework of MinNOx a workflow was developed for the efficient and quick generation of 3D CFD meshes for both the coolant flow region as well as the gas side of a combustion engine. In addition the tools which are now available enable the user to create FE meshes for the structural parts automatically.

Together with commercial FE codes like Abaqus the thermal analysis of gas water and metal can now be solved simultaneously resulting in more accurate temperature data specially for the combustion walls. This together with the improved turbulence modelling leads to highly accurate NOx predictions and enables the user to optimize e.g. combustion chamber shape, valve timings, intake flow swirl and tumble behaviour with regard to optimized emissions.
