Among the various heat transfer augmentation methods, passive techniques using surface or geometrical modification are extensively used. It increases the heat transfer rate without increasing the size and affecting the overall performance of the system. In this work, a computational fluid dynamics (CFD) model is developed which simulates the thermohydraulic performance of a pipe using twisted tape inserts and twisted tape inserts with perforations. Specifically, forced convection heat transfer through a pipe with inserts is numerically studied under a uniform/constant heat flux boundary condition with air as a working fluid. The simulation results are also compared with the experimental measurement.
