Validation and Verification of ANSYS Internal Combustion Engine Software

From 2012 Automotive Simulation World Congress: CFD software is regularly used to model flow inside internal combustion engines, including spray injection and injection combustion. Software verification and validation is a continual effort to ensure that the tools meet all design requirements and that computed results provide a high level of accuracy and performance. For complex simulations, various individual models are verified and validated, which can have a big impact on simulation results. The ANSYS validation and verification project for internal combustion engines includes a number of engines, both diesel and gasoline, in which simulation results are compared to experimental data.
