Numerical computation of the temperature field in the cylinder heads of modern high-speed diesel engines

The integration of numerical calculation methods is gaining importance in the layout process of modern high-speed diesel engines (HSDI). Higher demands are being made on the quality of the simulation results, especially with regard to the thermal structure analysis. This enforces the development of improved methods and simulation tools. In this process, heat transfer is of significant importance as the central issue.

Rechnerische Abbildung des Temperaturfelds in Zylinderköpfen moderner Dieselmotoren

Bei der Auslegung von Zylinderkopfen moderner Dieselmotoren nimmt die Integration von numerischen Berechnungsverfahren einen immer groseren Stellenwert ein. Besonders bei der thermischen Bauteilanalyse werden standig steigende Anspruche an die Qualitat der Simulationsergebnisse gestellt. Dies erfordert die Entwicklung von verbesserten Methoden und Simulationsmodellen. Dabei kommt dem Warmeubergang als zentralem Thema besondere Bedeutung zu.

Vehicle Thermal Management System Control Strategies – from MiL to HiL (CiL)

With the advancing progress of vehicle development, including the evolving of the overall vehicle systems itself, automobile development tasks are getting more and more complex. Thus, a holistic simulation of all systems in the vehicle becomes increasingly important during the engineering process for handling the multifaceted interdependencies among the systems correctly and more efficiently. As a consequence more complex multidisciplinary system simulations need to be implemented.
