摘要:

提出采用数值模拟的方法研究纵流壳程换热器,以克服实验研究方式的不足.利用相似理论,确定换热器的数值模拟模型,分析了各结构参数变化对其传热和流动性能的影响,结果表明:单排管间布杆、减小折流栅间距、增大管束长径比均有利于传热,但同时也增大了流动阻力;并利用最小二乘法,进一步回归出纵流壳程换热器层流下的传热和流动阻力的准数关联式.显示出采用数值模拟方式对换热器进行研究和开发的显著优点.

Abstract:

The numerical simulation method is proposed to study the longitudinal flow shell heat exchanger to overcome the shortcomings of the experimental research method. Using the similar theory, the numerical simulation model of the heat exchanger was determined, and the influence of the change of various structural parameters on its heat transfer and flow performance was analyzed, and the results showed that the rod arrangement between the single row of pipes, the reduction of the baffle grid spacing, and the increase of the tube bundle length-diameter ratio were all conducive to heat transfer, but at the same time, the flow resistance was also increased. The least squares method is used to further return the quasi-correlation of heat transfer and flow resistance under laminar flow of the longitudinal shell heat exchanger. It shows the significant advantages of using numerical simulation to research and develop heat exchangers.
