通过对气固多相流横掠光滑圆管与螺旋肋片管的总体和局部传热特性试验研究，利用气固多相流理论进行分析，来揭示气固多相流中颗粒对受热面传热强化机理。同时也利用二维Ｋ－ε模型模拟气流场以及ＦＳＲＴ模型模拟颗粒运动轨迹，建立气固多相流横掠光滑圆管传热模型。模型计算能与试验结果较好地吻合。图１３表１参１４ The general and local heat transfer characteristics of the gas-solid multiphase flow sweeping circular pipe and the spiral finned pipe were studied, and the gas-solid multiphase flow theory was used to reveal the influence of the particles in the gas-solid multiphase flow on the heat transfer Thermal strengthening mechanism. At the same time, the two-dimensional K-ε model was used to simulate the gas flow field and the FSRT model was used to simulate the particle trajectories. The model calculation can be in good agreement with the experimental results. Figure 13 Table 1 Reference 14
