在求解Abdel-Khalik建立的带蛇形管吸热板热迁移因子的矩阵微分方程时,得到了全部分析解,其中N=1的解,适用于求直管型平板集热器的F_(Ro)F_R可以表示为三个无因次数参((?)C_p/A_cu_L,F_(?)及F_2)的函数。对此我们编写了专门程序,由计算机绘制了通用无因次曲线,由它可直接查得F_(Ro)该方法比用传统方法确定F_R更方便、更准确,结果也更具普遍性。
When solving the matrix differential equation established by Abdel-Khalik with the heat transfer factor of a serpentine pipe heat sink, all analytic solutions are obtained. The solution of N = 1 is suitable for finding the F_ (Ro) ) F_R can be expressed as a function of three dimensionless parameters ((?) C_p / A_cu_L, F_ (?) And F_2). We have prepared a special program for this purpose. We draw a general dimensionless curve by computer, which can be used to directly search F_ (Ro). This method is more convenient, accurate and more universal than the traditional method to determine F_R.
