螺旋板式换热器高黏性介质换热特性的数值模拟

摘要

应用计算流体力学（ CFD）和数值传热学方法对螺旋板式换热器高黏性介质的传热特性进行了数值模拟。通过热流通道的润滑油、减压渣油和导热油3种介质与冷流通道的水模拟，计算传热系数和压降，并整合做出曲线。分析了不同黏度流体对螺旋板式换热器传热性能的影响。%We used the fluent software to study numerical simulation of heat transfer characteristics of high viscosity fluid in SHE.We simulated the heat transfer coefficient and calculated the pressure drop by simulating three kinds of fluid inclu-ding lubricating oil, vacuum residue and the heat conduction oil through heat channel and water through the cold channel. We analyzed the influence of the parameters of the spiral plate heat exchanger on internal flow resistance and heat transfer performance .
