Internal Combustion Engine Modeling

Course Duration: 2 Days

Prerequisites

Participants must be experienced STAR-CD V4.10 users.

Who Should Attend

This is an advanced class aimed at giving users an overview of spray, wall film and combustion modeling for simulation of Internal Combustion Engines. Principles of setting up and performing CFD calculations on SI and DI engines will be covered via a mixture of lectures and tutorials.
