1. Digital modeling tool

1.1 Different modeling approaches

To better understand the impact of thermal parameters on the fuel consumption and cabin heating performance of an automotive internal combustion engine, we need a numerical simulation tool. This tool for analyzing transient thermal phenomena has two functions. The first is to enable a precise study of sensitivity to cooling function control parameters, as highlighted in the dossier. , on energy exchanges and thermal balances within the engine. Its second function is to support the development of control and regulation strategies associated with the cooling system.

Historically, digital simulation is closely linked to the development of computer science, and took its first...
