The performance of heat exchanger depends on many parameters, one of the parameters is flow behavior of flowing fluid. Many of the researchers have performed different work to increase the performance of heat exchanger. In order to further increase the performance of heat exchanger, in this work perforated turbulators was used. In this work, through CFD analysis effect of different shapes of perforation on heat exchanger performance was analyzed. The numerical analysis of heat exchanger was performed with the help of Ansys (Fluent) software. For evaluating the effect of different shapes of perforation, four different shapes of perforation was considered that is circular, elliptical, triangular and rectangular. Also calculate the effect of change in Reynolds number for different shapes of perforation and considered 6000, 8000, 10000 and 12000 Reynolds number during numerical analysis. It calculates the value of Nusselt number, friction factor and thermal performance of heat exchanger having different shapes with different Reynolds number. Through analysis it is found that heat exchanger having triangular perforation shows an average of 22.9% heat transfer enhancement as compared to circular perforation.
