本文导出了单股射流系统局部换热系数和平均换热系数的经验公式。对多射流系统的两个方面进行了研究。一个主要涉及传热系数的均匀分布和功耗的经济性。另一个问题涉及到高的传热系数和射流之间的干扰。实验在雷诺数为103 ~ 104，孔径为1/8 ~ 1/4英寸的条件下进行。直径.试图将经验数据联系起来，使实际应用成为可能。
In this paper, empirical equations of local as well as average heat-transfer coefficients of single jet system were derived. Two aspects of multiple jet systems have been studied. One concerns mainly the uniform distribution of heat-transfer coefficients and economy of power consumption. The other concerns the high magnitude of heat-transfer coefficients and the interference among jets. The experiments were conducted at Reynolds number from 103to 104and hole size from 1/8 to 1/4 in. diameter. An attempt was made to correlate empirical data to render practical application possible.
