The parametric studies were applied under turbulent regime (2658? Re?7138) to monitor thermo-hydraulic performance of novel proposed design. The edge length of the pin fins (Lef) was varied regarding their diagonal length (5? Lef ? 6) while the pitch ratio (P/e) and twisting ratio were varied in the range of 0.75? P/e?1.0 and 50?TR? 200 respectively. By using the turbulent model SST k-? with low-Re correction model on ANSYS Fluent, the computational study has been carried out to discretize RANS equations. Average Nusselt number (Nu) and average Darcy friction factor (f) which define the thermo-hydraulic performance of system were elucidated in detail. As a result, the best thermo-hydraulic performance was achieved as 1.55 by using the lowest twisting ratio (TR=200), pitch ratio (p/e=0.75) and the highest diagonal length (Lef=6) and at Re=2658. © 2023, Toronto Metropolitan University.
