Abstract
This paper reports on the computation of the temperature distribution at the surface of the combustion chamber of a direct-injection diesel engine. The aim of these computations with ADINAT is to determine the temperature distribution, perturbated by the presence of measurement sensors, for the numerical calibration of these sensors. In addition, the temperature deviations caused by soot deposits on the surface are investigated; here the ADINAT results are compared to an analytical solution by a Fourier series approach. Furthermore software aspects are discussed that arise from the relatively large problems analysed here. A software environment for the new program system ADINAT in connection with existing pre- and postprocessors is described, the special requirements of large-scale problems and the resulting necessary modifications in the program are summarized, and finally the performance of ADINAT with respect to computational costs is studied in test computations.
