Modelling of vehicle thermal systems

摘要

Ricardo are leading a European Consortium (VTHERM) to develop new Computer Aided Engineering (CAE) methods which can be used to optimise vehicle thermal management. The VTHERM consortium consists of Ricardo, Fiat Research Centre, Dr. Schrick GmbH and Renault S.A. The objectives of the analytical approach are to improve system performance, to reduce procurement and testing costs for prototype systems and to significantly reduce vehicle development times. The basis for the VTHERM analysis tool is a detailed underhood air flow model and a 1-D thermal system model. These models may be run independently or linked to, enhance prediction accuracy for certain simulation cases. This paper discusses the system model approach and structure and presents a case study for a test vehicle used in the project.
