چکیده مقاله
Multi objective optimization studies of microchannel heat sinks MCHS frequently report peak performance at a single operating point without addressing the engineering questions that govern deployment: how robust is the optimal geometry, can performance be predicted without further CFD, which parameters truly drive the trade off, and how can the design be manufactured and scaled This paper bridges that gap for a hybrid MCHS combining oblique micro grooves with a circular micro pin fin array, optimized through a A simulation CFD driven MOGA II NSGA II based campaign over Rev The optimal designs converge to a robust window Wg,VY mm, L₁ = 9,1 mm, 0 = TA TO, Dp, mm , achieving a thermo hydraulic performance index of n = 1, 91, 1, a Y_9% Nusselt number enhancement, and a 1 1 % pressure drop reduction relative to the straight channel baseline A compact predictive correlation for n is developed and validated R2,9A, mean error 1,9% , and a data driven sensitivity analysis identifies groove width as the dominant driver of n VA % global importance and pin fin diameter as the principal hydraulic lever 20% The paper concludes with manufacturing feasibility considerations, a comparison with recent state of the art studies, and a four step implementation pathway toward industrial cold plates for power electronics, data center, and aerospace thermal management
