Multi-Objective Constructal Design for Square Heat-Generation Body with “Arrow-Shaped” High-Thermal-Conductivity Channel

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, Shannon entropy decision methods used to select results frontiers, deviation index was compare analyze advantages disadvantages of each method. At same time, constructal designs HTCC carried out through single degree freedom (DOF), two DOF, three respectively, thermal performance under optimizations different DOF compared. The show that design MOO method can achieve best compromise between resistance irreversible loss heat transfer body, thereby improving comprehensive body. vary increasing further improve HGBs.
