本文研究了气体横向冲刷清洁光管管束时的对流换热过程,分析比较了许多研究者提出的各种计算方法。作者对许多实验数据(错列管束和顺列管束各756组)进行了整理和归纳,并运用电子计算机进行回归分析,得到了两种计算错列和顺列管束对流换热的算式(多项表达式和指数表达式)。作者将所
In this paper, the convection heat transfer process of gas scouring and cleaning tube bundles is studied. Various calculation methods proposed by many researchers are analyzed and compared. The author has sorted out and summarized many experimental data (756 sets of staggered bundles and aligned bundles) and conducted regression analysis using electronic computers. Two formulas for calculating convection heat transfer between staggered and in-line bundles were obtained (polynomial expressions And exponent expressions). The author will
