Understanding and prediction of heat transfer between particle-laden turbulent flow and adjacent wall are of great interest in both applications and fundamentals. In this work, we employ direct numerical simulation and simultaneous Lagrangian tracking to study the influence of inertial particle with different particle thermal response time on heat transfer in particle-laden turbulent channel considering particle–turbulence momentum and energy interaction. As a result, the thermal feedback of the particle has always positive contribution to turbulent heat transfer and the thermal feedback effect gradually strength as the particles specific heat capacity increases.6 pagesPDF© 2014 University of Pretoria.
