The invention provides a passive self-adaptive automobile wake flow controller. The passive self-adaptive automobile wake flow controller structurally comprises an air inlet pipe, a turbulent flow pipe, a branch pipe and an air injection structure. The air inlet pipe is fixed to the bottom of the automobile and used for guiding airflow generated by relative movement in the automobile running process into the wake flow controller. After the turbulent flow pipe is connected to the air inlet pipe, an impeller is arranged in the turbulent flow pipe and used for conducting unsteady disturbance on airflow, and unsteady control airflow is generated. After the branch pipe is connected to the turbulent flow pipe, unsteady control airflow is divided into multiple strands of airflow, and multi-point control is achieved. The air injection structure is connected to the branch pipe, then arranged at the tail of the automobile and used for injecting the unsteady control airflow into the unstable airflow at the tail of the automobile, and wake flow control is achieved. According to the technical scheme, the unsteady flow control effect of the automobile wake flow is achieved through the simple structure, and different control effects can be provided in a self-adaptive mode according to the automobile speed.

    本申请提出了一种被动式自适应汽车尾流控制器,其结构包括进气管、扰流管、分路管和喷气结构。进气管固定于汽车底部,用于将车辆行驶过程中的相对运动产生的气流引入尾流控制器内。扰流管连接于进气管之后,内部设有叶轮,用于对气流进行非定常扰动,产生非定常的控制气流。分路管连接于扰流管之后,将非定常的控制气流分成多股气流,实现多点控制。喷气结构连接于分路管之后,设置于汽车尾部,用于将非定常的控制气流喷射到汽车尾部的不稳定气流中,实现对尾流的控制。该技术方案通过简单的结构实现了对汽车尾流的非定常流动控制效果,且能够自适应地根据车速提供不同的控制效果。
