Experimental investigation for heat transfer and friction coefficients has been performed for repeated-rib roughness in an annular turbulent air flow in which the inner surface is rough and the outer surface is smooth. The sectional shape of the ribs is trapezoidal. The relative rib spacing s/h varies in the range 8-17 and the Reynolds number in the range 1×104-1.5 ×105. The correlations for heat transfer and friction have been developed. The film heat transfer coefficients for rough annuli are 1.5-2.1...

Experimental investigation for heat transfer and friction coefficients has been performed for repeated-rib roughness in an annular turbulent air flow in which the inner surface is rough and the outer surface is smooth. The sectional shape of the ribs is trapezoidal. The relative rib spacing s/h varies in the range 8-17 and the Reynolds number in the range 1×104-1.5 ×105. The correlations for heat transfer and friction have been developed. The film heat transfer coefficients for rough annuli are 1.5-2.1 times that of smooth annulus. The thermal performance has been analysed.

本文对空气流过内管具有梯形重复肋的同心管湍流换热和流阻进行了实验研究,肋的相对间距s/h变化范围为8—17,雷诺数Re的范围为1×10~4—1.5×10~5,得到这种肋对于换热及流阻影响的规律,与光滑同心管实验进行了比较,换热系数为光滑管的1.5—2.1倍,对其热性能进行了分析.

In this paper the investigative results of the spray penetration of injector type ZS4S1 at ambient temperature, with back pressure and without turbulent air flow, by using the high speed photograph are given. Based on revising Hiroyasu equation a formula to calculate this type injector fule spray penetration has been proposed. It has been shown that results calculated by this way is coincide with experimental resuIts.

本文介绍了作者利用高速摄影在常温、有背压、无旋流条件下ZS4S1喷油嘴喷注贯穿距离的研究结果。在对広安博之公式进行修正的基础上,提出了此型喷油嘴喷注贯穿距离的计算公式。通过计算表明,按该公式预测的喷注贯穿距离与试验结果相吻合。
