چکیده
In the present paper , dynamic characteristics of the pressure pulsation and heat exchange have been analyzed in cooler of reciprocating compressor. Through the analysis of energy balance for an heat exchange element , the differential equations are established for the heat exchange element. Effect of the pressure pulsation on heat exchange has been considered in the cooler of the compressor by using a method of modified Reynolds number. The results· indicate that the pressure pulsation can enhance heat exchange in the cooler. INTRODUCTION Many researchers at home and abroad have done the work on eliminating the gas pulsation and piping vibration in compressor system. However, the gas pulsation may have benefit in compressor system sometimes. For example, it is indicated that the gas pulsation may enhance heat exchange [1]. On the basis of establishing the energy balance equations of differential elements for heat exchange of cooler, and revising the Reynolds number, the present work shows that the pressure pulsation enhances heat exchange in cooler of compressor.
