Abstract

Heat exchangers are used to transfer heat from one medium to another. Heat transfer depends on different process parameters of heat exchanger in which different types of turbulators were used inside the heat exchanger to increase the turbulence. Turbulators are used to increase the performance of heat exchanger, here in this work it uses discontinuous helical perforated turbulators at different Reynolds number to increase the performance of heat exchanger. For analysing the effect of different perforated turbulator here it considered three different types of perforated discontinuous helical turbulator that is rectangular, triangular and circular at 25 degree inclination angle. Here it calculate the value of Nusselt number, friction factor and thermal performance at different Reynolds number. Through analysis it is found that the discontinuous helical turbulator with triangular perforation shows maximum heat transfer.
