Three different tube shapes (namely circular, elliptic and drop-shaped) are considered at two transverse spacings; one of the spacings is similar to the one employed in typical industrial heat exchangers (e.g., at the lignite utility boilers of the Public Power Corporation of Greece,PPC).

在两个横向间距中，考虑使用三种不同形状的炉管；其中一个类似典型工业换热器所使用的间距（例如希腊公共电力公司，PPC的电站褐煤锅炉）。

Since the initial start of buried pipelines results in three-dimen-sional unstable heat transmission , and at initial start the temperature change of the soil around a pipeline is affected by the temperature inside the pipeline and the ground surface temperature annual fluctuation, the differential equation for heat transmission and the boundary value may be line...
