Abstract

In recent years, heat transfer enhancement of heat exchange equipment has attracted more and more attention. In this paper, the heat transfer and pressure drop characteristics of sine wavy flying-wing fins are studied by numerical method. The objective is to improve the integrated heat transfer and pressure drop performance of sine wavy flying-wing fins. The degrees of freedom of fin sizes include fin pitch to fin height ratio f/f, fin height to fin wavelength ratio f/W, fin amplitude to fin pitch ratio 2A/f and fin inclined angle α. The results show that among the calculated 17 flying-wing fins, the optimal values of f/f, f/W, 2A/f, and α are 0.5, 0.4, 1.9 and 70° respectively. The optimized SWFWF simulation model is established, and the average JF factor is 1.307, which is about 10.9% higher than that of Fin 05 (JF = 1.18). Multiple linear regression is used to obtain the correlations of flow and heat transfer characteristics of flying-wing fins. The average deviation of the correlations for j and f are 0.85% and 4.9% respectively. The correlations can be used for the design and optimization of sine wavy flying-wing fins.

摘要

近年来，热交换设备的强化传热越来越受到关注。本文采用数值方法研究了正弦波状飞翅肋片的传热和压降特性。目的是提高正弦波状飞翅肋片的综合传热和压降性能。肋片尺寸的自由度包括肋片间距与肋片高度之比f/f、肋片高度与肋片波长之比f/W、肋片振幅与肋片间距之比2A/f以及肋片倾斜角α。结果表明，在所计算的17种飞翅肋片中，f/f、f/W、2A/f和α的最优值分别为0.5、0.4、1.9和70°。建立了优化后的正弦波状飞翅肋片模拟模型，平均JF因子为1.307，比翅片05（JF = 1.18）高出约10.9%。采用多元线性回归得到了飞翅肋片流动和传热特性的关联式。j和f关联式的平均偏差分别为0.85%和4.9%。这些关联式可用于正弦波状飞翅肋片的设计和优化。
