“…Furthermore, they opined that the effects of circular fin pitch and the width of the fin were insignificant. Hithaish et al [11] numerically analyzed the hydrothermal characteristics of heat sink with triangular pin-fin at different orientations (30 𝑜 đ¶ to 60 𝑜 đ¶), height of the fin (0.25𝑚𝑚-0.75𝑚𝑚) and arrangements (alternate backward and forward). They revealed that HS with triangular pin fins in alternate forward and backward configuration had the highest value of the thermal performance index.…”

“…The ribs on the side walls have a limited effect on the boundary layer of the flow channel, and the cooling performance is improved more significantly by the addition of ribs or vortex generator configuration at the bottom (Datta et al, 2019). Many studies have investigated the effect of different configurations on minichannel cooling performance (Hithaish et al, 2022;Kim et al, 2022). Zheng et al studied the effect of the height arrangement of the ribs added at the bottom on the heat transfer coefficient in the microchannel flow channel and proposed an optimization method to obtain the optimal configuration (Zheng et al, 2022b).…”

“…The triangular pin-fin heat sink is therefore the central issue of this paper. Hithaish et al (2022). At present, there are many studies on the shape, height, number, and arrangement of vortex generators.…”

“…Pallikonda et al 18 found that elliptical fins in place of straight fins in the microchannel enhance the fluid mixing due to secondary flow, which disrupts the boundary layer and is optimum at 2° orientation. Hithaish et al 19 proposed, from their numerical investigation, that an alternate forward and backward arrangement outperforms all other configurations with a thermal performance index of range 1.01–1.44. Ganji et al 20 proposed Differential Transformation Method (DTM), an analytical approach, for solving a highly nonlinear differential equation, which defines a multimode heat transfer from a straight fin with variable thermal conductivity and found a good agreement with the conventional numerical methods, Galerkin and BVM method.…”
