Increased Effectiveness of Shell and Tube Parallel Flow Heat Exchanger by Varying Viscosity Ratio Using CFD Simulation

Vignesh.M

In previous designs fins were present only on inner side of the heat exchangers. In this design fins are present on both the inner side and outer side of the heat exchangers. By this the staying time of the cold fluid and hot fluid is increased which increases the heat transfer rate. Temperature difference and Viscosity ratio are noted for various cold and hot inlet velocities. Investigation is carried out by increasing number of tubes inside hot fluid path and overall heat transfer rate is calculated. The parameter for which heat transfer rate is maximum is taken as the optimized design. The angle of inclination of the fins on both inner side and outer side are varied for the same cold and hot inlet velocities. In the place of vertical baffles, helical baffles are placed and the heat transfer analysis is carried out. Simulation process is carried out by increasing the number of tubes inside the hot fluid path and overall heat transfer is calculated. The design for which the Viscosity ratio variation is maximum, can be taken as the optimized design for increased heat transfer rate.
