Based on the square heat-generation body (HGB) with “arrow-shaped” high-thermal-conductivity channel (HTCC) model established in previous literature, we performed multi-objective optimization (MOO) maximum temperature difference (MTD) minimization and entropy-generation rate (EGR) as objectives for its performance. Pareto frontiers optimal set were obtained based NSGA-II. TOPSIS, LINMAP, Shanno...
