文摘

Heat transfer in a dilute gas-particle suspension flow in multiple-slot impinging jets has beennumerically investigated using a new Eulerian-Lagrangian method that accounts for conductionheat transfer due to particle-wall collisions. The numerical results are compared with availableexperimental data. Good agreement between experiment and simulation is obtained only if theadditional conduction heat transfer due to particle-wall collisions is considered in the model.The effects of particle diameter, particle material properties and loading ratios, jet Reynoldsnumber, impingement wall temperature, and direction of the gravitation vector on heat transferare discussed.
