Efficient Sensitivity Analysis for Enhanced Heat Transfer Performance of Heat Sink with Swirl Flow Structure under One-Side Heating

Excellent heat transfer performance has increasingly become a key issue that needs to be solved urgently in the development process of large-scale fusion equipment. The study improvement scientifically and reasonably determine design parameters high flow (HHF) components reactors based on efficient in-depth analysis mechanism its sensitive factors is great significance. In this paper, liquid-vapor two-phase model with subcooled boiling for large length-diameter ratio swirl tube structure HHF calorimeter component proposed analyze effects (such as inlet temperature cooling water flow, parameters, etc.) performance. Then, considering computational cost model, order improve efficiency sensitivity these polynomial response surface surrogate function was constructed Latin hypercube sampling. On basis, by combining index each parameter could obtained efficiently using Sobol global method. This method greatly calculation reactor, which provides vital guidance subsequent rapid optimization related components.
