Comparison of the Thermohydraulic Efficiency of a Rectangular Fin Tube Heat Exchanger with or without Modified Rectangular Winglet Vortex Generator

Performance Evaluation Criteria (PEC)/ Thermo hydraulic efficiency of a Heat Exchanger may be increased using a Modified Rectangular Winglet Vortex Generator (MRWVG). This Modified rectangular Winglet Vortex Generator is fixed on a rectangular type fin plate and this plate is used to find the Performance Evaluation Criteria with the help of a wind tunnel. The wind tunnel test rig is used for calculating the experimental data with and without a rectangular winglet vortex generator. In this test section first, take a reading on the rectangular plate without the modified rectangular winglet Vortex Generator, and then after fixing the modified rectangular winglet and all experimental repeats same with the modified rectangular winglet Vortex Generator to find PEC. The maximum PEC is calculated experimentally for both with or without using the modified rectangular winglet and after that, a comparison should be done and find the maximum Performance Evaluation Criteria.
