The conversion, utilization and recovery of energy in every industrial, commercial and domestic application involve a heat exchanger process some common example are steam generation and condensation in power and co-generation plants, sensible heating and cooling of viscous media in thermal processing of chemical, pharmaceutical and agricultural products, refrigerant evaporation and condensation in air conditioning and refrigeration gas flow heating in manufacturing and waste heat recovery air and liquid cooling of engine of electrical machine and electronic devices. improved heat exchange of standard practice can significantly improve the thermal efficiency in such application as well as the economically of their design and operation. Double pipe heat exchanger (DPHE) is one of the most simple and application heat exchanger. This kind of heat exchanger is widely used in chemical food oil and gas industries. Double pipe heat exchanger is having a relatively small diameter and it is easy to fabricate as compare to helical tube and many more compact tube of heat exchanger. Commonly method used by the reaches to enhance the heat flow rate is active method, passive method and compound method and present work is based on passive method. In the present work experiment is carried out on plane double pipe heat exchanger and corrugated tube double pipe heat exchanger in which hot water is flowing though inner tube where cold water is flowing though the annulus and hot water to cold water heat exchange is taken in consideration. During the experiment cold water flow rate is kept constant at 45 LPH, where as hot water flow rate varies from 15 LPH to 75 LPH in all two cases........
