Effects of Thermal Boundary Condition, Fin Size, Spacing, Tip Clearance, and Material on Pressure Drop, Heat Transfer, and Entropy Generation Optimization for Forced Convection from a Variable-Height Shrouded Fin Array

Entropy generation and optimization of laminar convective heat transfer and fluid flow in a microchannel with staggered arrays of pin fin structure with tip clearance

“…The authors [20] further found that increasing side/top clearance reduces the dimensionless entropy generation rate. Famouri et al [33] reported the effects of fin size, spacing and tip clearance. The impact of fin material was also included by solving a conjugated conduction-convection problem with isothermal and constant heat flux wall boundaries.…”

Thermal-hydraulic performance of interrupted microchannel heat sinks with different rib geometries in transverse microchambers

“…Xie et al [32] used the relationship between the thermal resistance and the pumping power to evaluate the heat transfer enhancement of the microchannel heat sinks with internal vertical Y-shaped bifurcations. Khan et al [33], Famouri et al [34], Shi and Dong [35], Zhai et al [36], and Chai et al [37] developed optimization methods based on entropy generation minimization, which was proposed by Bejan [38] for the first time, to study the optimization of thermal and hydraulic resistances simultaneously with all relevant design parameters for microchannel heat sinks including geometric parameters, material properties and flow conditions. Promvonge et al [39], Xia et al [40,41], Chai et al [13,37], and Zhang et al [42] used the performance evaluation criteria (PEC) to comprehensively access the heat transfer performance of their proposed microchannel heat sinks.…”

Parametric study on thermal and hydraulic characteristics of laminar flow in microchannel heat sink with fan-shaped ribs on sidewalls – Part 1: Heat transfer

“…For further study the optimization of thermal and hydraulic resistances simultaneously with all relevant design parameters for microchannel heat sinks including geometric parameters, material properties and flow conditions, Xie et al [17] used the relationship between the thermal resistance and the pumping power to evaluate the heat transfer enhancement performance of the microchannel heat sinks with internal vertical Y-shaped bifurcations. Famouri et al [18] and Shi and Dong [19] applied optimization methods based on entropy generation minimization for the optimization of a variable-height shrouded fin array and microchannel with staggered arrays of pin fin structure, respectively.…”
