Abstract

To evaluate the wall heat losses in combustion vessel, an alternative to existing macroscopic models of heat transfer is suggested. This study aims to provide a physical approach for wall heat transfer based on kinetic theory of gases to describe the conduction phenomena between gas particles and the cold wall in short scales. The model mentioned is implemented in a code simulating combustion in a constant volume spherical chamber.
