| 摘 要： | 对恒壁温加热条件下水平管内空气-煤粉混合物的两相对流传热进行了数值模拟和试验研究。数值模拟结果表明：壁面总传热量和壁面与固体粉末间的传热量都随着固相颗粒直径的增大而减少、随着煤粉体积率的增大而增大,而固相颗粒直径和煤粉体积率对壁面与气体间的传热量的影响不大;对流传热的Nusselt数（Nu）随着Reynold数（Rem... |

| Abstract: | The convection heat transfer of air-coal powder mixture flow inside a horizontal tube under the condition of constant wall temperature was simulated and investigated experimentally.The simulation results showed the total heat flow rates of wall and wall to coal powder decreased with increasing of the solid powder diameter and increased with increasing solid volume rate while there was less influence of powder diameter and volume of solid on the heat transfer flow rate from wall to air.The Nusselt number of ... |
| Keywords: | constant wall temperature horizontal tube air-coal powder mixture two phase convection heat transfer |
