Abstract
Heat exchanger as the name indicates it transfers heat from one fluid to another which is at different temperatures. Heat exchangers are devices built for efficient transfer of heat from one fluid to another and are widely used in engineering processes. Some examples are intercoolers, pre-heaters, boilers and condensers in power plants. The heat transfer efficiency depends on both design of heat exchanger and property of working fluid. In this paper, the heat transfer rate is improved by inserting the slotted twisted strip in the heat exchanger & comparison is done for both parallel & counter flow. The result shows that inserting the slotted twisted strip in heat exchanger increases the turbulence in fluid flow, which increases the heat transfer rate.
