The measured results were compared to simulation results.
Simulation.
These values are in agreement with a preliminary simulation of the high pressure gas quenching using the CFD-program Fluent [12].
A 3 dimensional simulation of the case hardening process using a position dependent heat transfer coefficient taken from a CFD-simulation of the gas flow may also help improving the results.
In order to improve the simulation results, 3 dimensional simulations with enhanced streaming simulation of the gas quenching process should be employed.
