A multi-parameter optimization software tool for active cooling panel with high thermal load is established and validated. It can be quickly solved in the constraint range and setting margin, and automatically select the basic geometry size. The minimum mass for active cooling structure matching the complex thermal environment and fuel cooling capacity of the engine is obtained. With the minimum mass as the optimization objective, the constraints such as the allowable stress of the structure, the allowable temperature of the structure, the coking temperature of the cooling fuel, the loss of the cooling fuel flow resistance and the processing limit are considered. The material is available in the thermal environment with a gas convection heat transfer coefficient of 445∼1800W/m2-K. The feasible solution is converted into a material design space map, which can be used to compare a variety of materials to the safety margin of a given active cooling structure, or to intuitively compare the feasibility of a given material to a variety of active cooling structures. Using these design space maps, the active cooling structure design can be quickly determined according to the given conditions. The feasible solution can be converted to a material weight map, and a minimum weight structural scheme can be visually determined from a variety of scenarios. |
