采用电流体力学（EHD）技术，对管壳式气-气换热器中七管组管侧和壳侧的传热强化率控制进行了实验研究。采用一种新的方法，证明了每个管中的电流以及相应的传热强化可以独立控制，并进行了三系列实验。第一个系列涉及当电场仅作用于热交换器的管侧时，传热和压降特性的评估。 第二和第三系列实验分别涉及壳侧激励和管侧和壳侧同时激励。在每一种情况下，研究了雷诺数和管壳侧施加电流对增强效果的影响。研究发现，在最低雷诺数和最高外加电流下，增强效果最高。管壁和壳壁的同时激励导致整体传热系数的最大增强。 关键词:热流、换热器、气体、管壳式换热器、实验、计算、测试、压降、特性、传热系数、雷诺数。引用:研讨会，ASHRAE Trans。1994年，第100卷，第一部分

The control of heat transfer enhancement rates on the tube and shell sides of a bank of seven tubes in a shell-and-tube, gas-to-gas heat exchanger was investigated experimentally with the use of the electrohydrodynamic (EHD) technique. Using a novel method, it was demonstrated that the current in each tube, and therefore the corresponding heat transfer enhancement, can be controlled independently, Three series of experiments were performed. The first series involved evaluation of heat transfer and pressure drop characteristics when the electric field was applied to the tube side only of the heat exchanger. The second and third series of experiments involved excitation of the shell side only and simultaneous excitation of the tube and shell sides, respectively. In each case, enhancements were studied as a function of the Reynolds number and applied electric current in the tube and shell sides. It was found that enhancements were highest at the lowest Reynolds number and at the highest applied current. The simultaneous excitation of the tube and shell sides led to maximum enhancement in the overall heat transfer coefficient.KEYWORDS: heat flow, heat exchangers, gas, shell and tube heat exchangers, experiment, calculating, testing, pressure drop, properties, heat transfer coefficient, Reynolds numbers.
