| 摘 要： | 对气－固多相流动中颗粒对边界层的影响进行了定性分析，提出了颗粒对边界层作 用的三区域模型，即加厚区、临界区、减薄区。根据该模型分析了气－固多相流对流换热机理， 为气－固多相流传热问题的研究进行了积极的探讨。

| Abstract: | The paper qualitatively analyzes the effects of particles on gas boundary layer, and develops a three action areas model, namely, thicken area, critical area and thinen area. Based on this model, the paper also discusses the mechanism of effects of particles on convective heat transfer in gas-solid multiphase flow, and provides the positive exploration to solve.the problem of the heat transfer in gas-solid multiphase flow. |
