The optimum tubespacing equals approximately to the departure diameter of the bubbles during a pool boiling.
最佳管距对应的管束水力当量直径近似等于池内沸腾时的气泡脱离直径。

The comparison of heat transfer performance with three different fin spacing, three different Numbers of tube rows and three different Numbers of tubes under three constraints is carried out.
然后通过三种限制条件对不同翅片间距、不同管排数和不同管数下的换热板芯的传热性能进行了比较。

Within the range of experiment, increasing fin height or decreasing spacing of fins of petal-shaped fin tube is helpful to improve the performance of heat transfer enhancement.
