Thermal shock testing for Engines in Dymola
Alessandro Picarelli, Eduardo Galindo, Gonzalo Diaz · Linköping electronic conference proceedings · 2014
In this work, we use an acausal multi-domain physical system model to study the interaction between an internal combustion engine operation and a range of cooling scenarios.Although the model can be used for modelling a wide range of scenarios, in this paper we concentrate on the application of "thermal shock".An internal combustion engine is loadcontrolled on a dynamometer and coolant temperature transients are imposed on the engine system.Using freely available and commercial Modelica Libraries within the Dymola environment, the whole system integration of the coolant rig and engine dynamometer is achieved.This allows the user to develop and define control strategies for the tests from desktop, prior to engaging in the real tests.
