为了探究高空低雷诺数条件下吸附式叶型的气动设计特性,利用人工蜂群算法对低雷诺数吸附式叶型进行优化设计,该设计方法可以将叶型和抽吸方案进行耦合优化.并且对高空低雷诺数吸附式叶型耦合优化设计的必要性进行了论证.研究结果表明:在地面条件下设计的具有较好性能的吸附式叶型,在高空低雷诺数条件下,性能有可能会显著下降,针对高空低雷诺数条件的吸附式叶型设计有很大必要性;针对研究对象,在高空低雷诺数条件下优化设计后总压损失降低了32%,静压升提高了0.01,并且优化设计后在地面条件下的性能也略有提升;在高空低雷诺数条件下,适当地增加吸附式叶型前段的负荷,通过抽吸来控制层流分离泡的设计效果最为理想;优化后得到的最佳抽吸位置位于层流分离泡中心区域.
In order to explore the aerodynamic design characteristics of the adsorptive aerofoil at high altitude and low Reynolds number, an artificial bee colony algorithm was used to optimize the design of low Reynolds number adsorptive aerodynamic force. This design method can be used to optimize the aerodynamic and aerodynamic characteristics The necessity of high-altitude low Reynolds number adsorption leaf-type coupling optimization design is demonstrated.The results show that the adsorption leaf type with better performance designed under the ground conditions has the possibility of performance under high altitude and low Reynolds number conditions There is a great need for the design of adsorption leaf at high and low Reynolds number conditions. For the research object, under the conditions of high altitude and low Reynolds number, the total pressure loss is reduced by 32% and the static pressure rise is increased by 0.01 , And the performance under optimized ground conditions is slightly improved. Under the conditions of low altitude and low Reynolds number, it is most desirable to appropriately increase the load of the front section of the adsorptive blade and to control the design of the laminar bubble by suction. The optimal pumping position after optimization is located in the center of the laminar flow separation bubble.
