Riassunto analitico

This master thesis developed from the idea to combine a three-dimensional exhaust manifold geometry and a monodimensional full model of an engine with integrated exhaust manifold to get a coupled model.
The concept is to replace the calibration process with a coupled simulation to get reliable results through a faster procedure.
The three-dimensional exhaust manifold geometry has been integrated into the monodimensional model using Converge Lite as a three-dimensional solver.
Consequently, StarCCM+ replaced Converge-Lite as the three-dimensional solver in the coupled model because it was required a more sophisticated set of parameters.
The project focused the attention both on 1D results and 3D results in order to modify the base exhaust manifold design to optimise the flow.

Abstract

This master thesis developed from the idea to combine a three-dimensional exhaust manifold geometry and a monodimensional full model of an engine with integrated exhaust manifold to get a coupled model. The concept is to replace the calibration process with a coupled simulation to get reliable results through a faster procedure. The three-dimensional exhaust manifold geometry has been integrated into the monodimensional model using Converge Lite as a three-dimensional solver. Consequently, StarCCM+ replaced Converge-Lite as the three-dimensional solver in the coupled model because it was required a more sophisticated set of parameters. The project focused the attention both on 1D results and 3D results in order to modify the base exhaust manifold design to optimise the flow.
