This paper presents a coupling of the Monte Carlo method with computational fluid dynamics (CFD) to analyze flow channel design an irradiated target through numerical simulations. A novel series configuration is proposed, which effectively facilitates removal heat generated by high-power irradiation from without necessitating increase in cooling water rate. The research assesses performance both parallel and serial channels within target, revealing that, when subjected equivalent rates, maximum temperature observed employing lower. reduction ascribed accelerated channel, subsequently elevates Reynolds number Nusselt number, leading enhanced transfer efficiency. Furthermore, occur further downstream, thereby circumventing areas peak generation. phenomenon arises because traverses plates highest internal generation at lower are arranged series, optimizing effect on these targets. However, it crucial note that pressure loss associated structure two orders magnitude greater than structure, increased pump power imposing stricter requirements container pipeline. These findings can serve as reference for station system, particularly light anticipated beam during second phase China Spallation Neutron Source (CSNS Ⅱ).
