Abstract: Shot peening is a well-established surface treatment that is widely used in industry for improvement of fatigue performance of metal components. Numerical methods have shown great potential to achieve significant cost and time reductions during shot peening process development. In this study, Open source Field Operation and Manipulation (OpenFOAM) has been applied to the shot peening application. The initial stage of the work involved building a model that can predict in-flight media particle velocity and impact locations on the workpiece. Experimental results were used to validate the solvers. Preliminary results suggest good agreement for media particle velocity and impact coverage between the results from the OpenFOAM solver and experimental work. In addition, the OpenFOAM flow field was also compared to ANSYS-FLUENT results and showed only minor differences. Current results suggest that the model can be used to further improve the nozzle design.
