A heat exchanger is usually a device employed to transfer heat amongst a solid object and simply a fluid or between two or even more fluids. The fluids could possibly be segregated by a solid wall to eliminate mixing or they may possibly be in direct contact. The rate by which heat transfers is reliant on the conductivity concerning the separating wall and then convective heat transfer coefficient between the wall and simply fluids. In order to increase the heat transfer rate different types of baffles were used inside the heat exchanger. Here in this work discontinuous perforated helical turbulators were used to increase heat transfer rate. Here in this work it calculate the effect of different helix angle on heat transfer, for analysing the effect of helix angle five different helix angle that is 8, 10, 12, 14 and 16 degree were considered and calculate the value of Nusselt number, friction factor and thermal performance for different helix angle. After finding the optimum helix angle here it also calculated the effect of change pitch in between two perforated helical turbulator. For calculating the effect of different pitch it considered six different pitches that are 6.5, 5.83, 4.5, 2.92, 1.83 and 1.5 with a constant optimum helix angle of helical turbulator. Also finding the effect of change in Reynolds number on heat transfer, here it considered four different Reynolds number that are 6000, 80000, 10000 and 12000.
