Guidance page for practical work 20: Diesel engine model and driver (setting out and correction)


We model a diesel engine by a mixed cycle taking into account a three-phase combustion as well as the evolution of the thermodynamic properties of the fluid.

The modeling is performed in two stages: initially, the model is set "by hand", using the basic features of Thermoptim, and then in a second step, an external driver automatically ensures a consistent setting of parameters.

This guidance page studies the operation of diesel engines and shows how they can be realistically modeled with Thermoptim.

The practical work starts with the modeling presented in session S38En , and then shows how can be built an external driver to automate the setting of the cycle parameters.

You will find below the document in pdf format, and an archive containing the files you need to build your models
