課程簡介

Today’s automotive products have to be in line with the automotive industry's megatrends that make driving safer, more comfortable and more sustainable. High performance products, such as Navigation-, Multimedia-, Telematics-Systems, Instrument Cluster and Head-Up Displays will make Individual mobility more comfortable. Products, focusing on driving safety, collision avoidance and protection during accidents will make individual mobility saver and additionally more sustainable, when products help to reduce fuel consumption and emissions.The design of these highly complex automotive systems requires the interaction of mechanical, electrical and software engineers in order to fulfill requirements from mechanical stability and thermal management to electromagnetic compliance within a wide range of ambient temperatures and environmental conditions. The consequent employment of computer-based simulation, such as thermal simulation, supports the exploitation of a design’s potential, enables the comparison of different concepts and variants and contributes to numerically supported design decisions. Such up-front simulations, also called virtual analyses, an integral part of the design process, enable us to test and modify system and components as virtual prototypes before performing physical tests and building real prototypes.

課程目標

In this presentation we focus on typical tasks and problems involved in the thermal design and simulation of such systems for automotive applications. A Computational Fluid Dynamics (CFD-) program is necessary to simulate heat transfer and air flow concurrently. Employed is the commercial CFD-program FLOTHERM (Mentor Graphics) to simulate the three cooling mechanism conduction, convection, radiation.
