Abstract Aviation, marine propulsion, and power generation employ gas turbine engines extensively. The combustion process’s high temperatures make engine development difficult. For safe blade operation, internal cooling is essential. Ribs, pin-fins, impinging jets are just examples of the several different types structures that typically included in systems. present study investigates effect rib placed between pin fins a wedge channel. Nine configurations along with base line model without ribs employed this study. SST k-omega turbulence was to simulate flow field heat transfer each case using commercial software ANSYS Fluent. investigation demonstrated distribution pin-fin arrays were substantially influenced by ribs-induced secondary flows, particularly spanwise direction, which resulted significant variation. In comparison other configurations, 4H4L configuration exhibits highest thermal performance factor, surpassing baseline approximately 16.6 %.
