Pin-fin cooling is a significant method for managing high temperatures in gas turbine blades during operation. This study recommends the employment of pencil-shaped and circular pin fin to improve channel's heat transfer efficiency, based on both experimental computational examinations. Numerical simulations with Reynolds numbers ranging from 10,000 80,000 are used explore compare flow properties wedge channel three rows staggered pencil circular-shaped fins diameter 12 mm. The investigation revealed that arrangement affects pattern differently. Compared fins, enhanced by 11.72%, pressure drop minimized 72.2%. Furthermore, compared smooth channel, Nusselt number shows an increase 40%. When comparing increases 18%. As result thermal performance factor 35.2%.

Adding obstacles and obstructing fluid flow in cooling channel to induce whirl velocity enhances thermal performance heat sinks. An analysis is presented of conjugate transfer a sink with transversely inserted bars the channel. The numerical study seeks maximise dimensionless conductance subject constant total volume. contrasts standard without bar inserts one, two, three, 4 bars. To improve surface area for transfer, extended surfaces are placed longitudinally at various points A high-density flux applied bottom wall coolant an inlet vin between 4.26 7.26 m/s pumped forced convective laminar condition eliminate heat. computational dynamic (CFD) code incorporated Ansys fluent used solve mathematical models. indicates that configuration featuring 3 roof exhibits highest global conductance, achieving 53 % increase over other configurations. All configurations up, down, left right, maintain pump power 3.5 W across Reynolds number range 857–1461. Bars positioned experience lowest outlet inner temperatures, whereas those floor exhibit temperatures. optimised design meets porosity limit 0.8.
