摘要：

The steady, fully developed heat transfer to the walls of a vertical pipe from a dilute suspension of relatively massive particles of low Biot number in a turbulent gas is analyzed. In this flow. particle collisions play a significant role. The thermal energies of the particle and gas phases are balanced using two coupled equations. In the particle phase, conduction is calculated from the kinetic theory as a self-diffusive transport flux and, assuming negligible transfer of heat during collisions, homogeneous boundary conditions are prescribed for the temperature. Solutions of the balance laws highlight the mechanisms governing the heat transfer in this regime.
