Abstract in another language

The aim of this project is a complete yet simple numerical model for the heat transfer in a system of exhaust pipes of an automobile. The industrial partner Tenneco Automotive, H. Gillet GmbH at Edenkoben, uses this simulation for optimising the construction of the exhaust system in order to improve the efficiency of the catalytic converters. In this model forced convection of the exhaust gas, the heat conduction and the heat transfer due to radiation are taken into account. For the effective numerical solution of the boundary integral equation for the radiation heat transfer a method that is based on matrix compression is developed. Some numerical examples for the matrix compression and calculations using a developed software package are presented.
