Analysis on CFD-simulations in internal combustion engine nozzle injector with different shape

In this study, the benefits, challenges and conditions of using parametric CADmodels for aiding CFD-simulations and performance-optimization in the product development within internal combustion engines have been assessed. The goal of the present study is included developing and proposing a methodology for design engineers at Scania which will aid them in creating parametric CAD-models which are robust, flexible, comprehensible and intelligent. The two different types of injectors were designed by 3D modeling software and evaluate the thermal and structural properties.
