The calculation results show that the entropy generation per unit heat transfer rate (△ S / Q ) increases gently with increasing corrugation angle of the fin but is nearly independent of the fin pitch. 计算结果表明:换热器单位换热量的料熵产随翅片波纹角的增加略有增加,但几乎不受翅片间隔的影响。
The Model of Error Entropy of Area Unit in GIS GIS中面元的误差熵模型
In tnis paper an analytical method is proposed to predict the distribu-tion of the rate of entropy generation per unit volume in the boundary layer by means of the simultaneous solution of continuity, momentum, energy and entropy differential equations. 本文通过连续方程、动量方程、能量方程和熵方程的联立求解,对于对流换热边界层内单位体积熵产生率的分布,提出了一种计算方法。
Finally, using simulating and contrast methods and through cases, the entropy synergies of C2 UNIT " group " was verified, and how the synergies affected by the decision-making time and the quality of information was explained. 并通过案例,采用仿真和对比的方法,验证指控单元群的熵协同效果,说明决策时间以及信息质量如何影响协同效果。
In order to measure the area unit's positional uncertainty, the average entropy band of line segments is firstly presented based on average entropy of the whole line in this paper, and then is extended to error entropy donut of area unit. 根据整个线元边缘分布的平均信息熵确定了ε带的宽度,提出了线元的平均误差熵带模型,进一步扩展到面元的误差熵环模型。
