At the end of the course students should have high-level knowledge on models and simulation methodologies for the 3D-CFD analysis of the thermo-fluid dynamic processes in propulsion systems and components for automotive and heavy duty applications (internal combustion engines, electric motors, fuel cells). Students should have basic knowledge on numerics and numerical solution of fluid-dynamic and electro-chemical problems, chemical kinetics, optimization. Students should demonstrate high-level knowledge on models and simulation methodologies for the 3D-CFD analysis of the thermo-fluid dynamics and in particular a basic knowledge on the use of some widely used commercial tools for the specific applications with the target to obtain engineering-wise solutions for complex fluid-dynamic problems in the fields of internal combustion engines, heat transfer, e-motors and fuel cells.

Admission requirements


Course contents

- fuel spray models and simulation (0.4 CFU)
- combustion models and simulation (0.4 CFU)
- heat exchange models and simulation and multiphase flows (0.4 CFU)
- conjugate het transfer in eletric motors and machines (0.2 CFU)
- electro-chemical modelling of fuel cells (0.4 CFU)
- basic knowledge of chemical kinetics of fuels (0.1 CFU)
- basic knowledge of optimization techniques (0.1 CFU)
- use of "state of the art" commercial tool: STAR-CCM+ (6 CFU)

Teaching methods

Teaching will be carried out exclusively face to face, unless variations due to the COBD-19 situation. Lessons on CFD theory: The CFD theory will be taught only face to face unless health and security issues related to the COVID19 situation will emerge. Hands on the software lab tests on ICEs cases: Part of the "hands on the SW" laboratory lessons will be given face to face through virtual machines and local installations on the students' PCs of the adopted SW calling remote licenses provided by the teachers. A possible closing project following the "student competition" structure is under discussion.

Assessment methods

Preliminary test on the use of 3D-CFD tools: Minimum score 4/30, maximum score 12/30 Oral exam on theoretical concepts/topics: Maximum score 20/30 The overall rating is the sum of the scores obtained in the two tests. To pass the exam the overall score must be higher than 18/30. If the total score exceeds 30/30 the overall rating should be 30 with honors. Both tests and oral exams may be given either in person or remotely following the evolution of the COVID19 situation.
