Heat Transfer Enhancement in Double Pipe Heat Exchanger with Twisted Type Inserts In ANSYS Fluent

  G.Nagarajan,  S.Ranganathan

The study deals with CFD simulation of concentric tube heat exchanger and concentric tube heat exchanger with insert used for heating air using ANSYS FLUENT Software for steel. Nowadays, heat exchangers with twisted-tape inserts have widely been applied for enhancing the convective heat transfer in various industries such as thermal power plants, chemical processing plants, air conditioning equipment, refrigerators, petrochemical, biomedical and food processing plants. In general, twisted tape insert introduces swirl into the bulk flow which consequently disrupts a thermal boundary layer on the tube surface. In general, twisted tape insert introduces swirl into the bulk flow which consequently disrupts a thermal boundary layer on the tube surface. Design process for heat exchanger and insert has been carried out in solid works fluid domain is formed in ANSYS workbench, followed by meshing in default mesh tool of ANSYS and solution is developed using ANSYS Fluent software as Finite element tool and the results are compared between the two designs for parallel flow.

Keywords- Double pipe heat exchanger, Insert, ANSYS Fluent, Twisted tape insert.
