通过分析对流换热过程中微元控制体内的(火积)流动平衡,得到类似于热传导过程中(火积)耗散函数表达形式的对流换热准(火积)耗散函数,表明对流换热过程中的(火积)耗散由热传导和对流形成的耗散共同构成。并通过分析对流换热过程的特点,对准(火积)耗散函数中对流项的影响进行了修正,使用圆管内热充分发展流动与无限宽平行通道内的对流换热过程检验,控制体内准(火积)耗散函数的计算结果与边界(火积)流的结果一致,表明文中提出的准(火积)耗散函数是可靠的。
The convection heat transfer (FA) dissipation function, which is similar to the expression of the (fire product) dissipation function in the heat conduction process, is obtained through the analysis of the (fire product) flow equilibrium in the micro- The (fire product) dissipation in the thermal process consists of the dissipation of heat conduction and convection. By analyzing the characteristics of the convective heat transfer process, the influence of the convection term in the quasi (fire product) dissipation function is corrected. The internal heat transfer in the circular tube and the convection heat transfer in the infinite parallel channel are used to control the in vivo The results of the quasi (fire product) dissipation function are consistent with the results of the boundary (fire product) flow, which shows that the quasi (fire product) dissipation function proposed in the paper is reliable.
