Heat transfer characteristics of plate fin heat sink with longitudinal vortex generators

Purpose This study aims to provide an insight into the relationship between design parameters and thermal performance of plate fin heat sinks (PFHSs) incorporating longitudinal vortex generators (VGs) inside a PFHS channel. Design/methodology/approach A computational fluid dynamics model delta winglet pair VG mounted geometry is detailed, validated by comparison with experimental data. The used perform virtual experiments sink bottom vertical VGs. Data from this regress response surface enabling influence each assessed variables on flow resistance be determined. Findings results show that hydraulic performances are, respectively, 1.12 1.17 times higher than baseline PFHS. Further, variation VG, relative winglet’s arrangement (common up common down), trailing edge gap length Reynolds number were also evaluated reported. Originality/value For first time, characteristics VGs are against different polynomial regression developed. developed computed can high PFHSs
