摘　　要：根据段塞流特点,建立段塞流传热模型,模型计算得到的平均传热系数理论值与实验得到的传热系数实验值符合得很好,误差在10%以内,与其它模型对比,段塞流传热模型更接近实际情况。分析了液体、气体流量对传热系数的影响,传热规律实验结果表明:段塞流下气液流量(流速)与对流换热系数呈线性关系,液体流量是影响传热的主要因素。In the light of the specific features of a slug flow,established was a heat transfer model for slug flows.The theoretical value of the average heat transfer coefficient calculated by using the model is in very good agreement with that of the test one with the error being within 10%.Compared with other models,the heat transfer model for slug flows is more close to the actual conditions.In addition,the authors have also analyzed the influence of the fluid and gas flow rate on the heat transfer coefficient.The heat transfer law test results show that the gas and fluid flow rate(speed) under a slug flow and the convection heat exchange coefficient assume a linear relationship and the fluid flow rate is regarded as the main factor influencing the heat transfer.
