The heat transfer between particles and walls plays an important role in several industrial processes. Since established models often deal with simplifications for the surrounding gaseous phase, this work aims to acquire a fundamental understanding of the occurring transport phenomena. In this work, a high-resolved finite-volume method is applied carrying out direct numerical simulation of fluid dynamics and heat transfer simultaneously. The influence of turbulence on the heat transfer is discussed in this paper.
