Based on the thermohydraulic calculation model verified in this study and Non-dominated Sorted Genetic Algorithm-II (NSGA-II). a multi-objective configuration optimization method is proposed. and the performances of shell-and-tube heat exchanger with disc-and-doughnut baffles (STHX-DDB) and shell-and-tube heat exchanger with segmental baffles (STHX-SB) are compared after optimization.... https://www.roneverhart.com/Grace-Design-M801-MK2-High-Fidelity-p15168/
