Abstract

This paper develops the general theory to predict thermal boundary conditions from known temperatures at internal specific points in domain by the boundary element method, and with practical application in calculating boundary conditions on inner walls of engine cylinders. The numerical procedure presented has the advantages of discretizing only at the boundary. An example of thermal boundary conditions inside the cylinder of a high-speed air-cooled and four-stroke engine, shows that the procedure is effective and agreement between experimental data and numerical values for several internal temperatures could be obtained within 5%.
