Abstract

Abstract:

The plate heat exchangers are widely used in industrial applications. A novel honeycombed plate heat exchanger is experimentally and numerically investigated in this research. The numerical results have been validated with the experimental values at a reasonable range. The internal velocity field of novel honeycombed plate heat exchanger is changed periodically, which increase the fluid turbulence intensity. The experimental results indicate that the entransy-dissipation is inversely related to its thermal resistance in novel honeycombed plate heat exchanger. The results of the current study provide a useful reference data for future design optimization of the novel honeycombed plate heat exchanger.

Key words: plate heat exchanger, heat transfer enhancement, entransy dissipation resistance, numerical simulation, experimental validation

摘要：

板式换热器在工业生产中广泛应用。基于换热器(火积)耗散热阻理论，采用数值模拟和实验相结合的方法对新型蜂窝板式换热器进行研究。结果表明数值模拟和实验结果在合理的误差范围内，验证了数值模拟的可靠性。新型板式换热器内部蜂窝结构附近的速度场出现规律的周期性变化，流体湍流强度增加，提高了换热效率。新型板式换热器换热量与其(火积)耗散和(火积)耗散热阻呈反比例关系，这为新型蜂窝板式换热器的优化提供了理论依据，并为工业生产提供参考。
