Study on low speed primary jet vector controlled by synthetic jet actuator with an inclination angle

Based on an overall flow field calculation model-X-L model, numerical analysis and mechanism investigation is carried out for a low speed primary jet vector controlled by synthetic jet actuator. The result shows that the synthetic jet actuator with an inclination angle can effectively control low speed primary jet vector and the primary jet direction can be changed greatly by altering the angle without increasing input power. The working parameters and actuator location have the optimal value in affecting primary jet vector regularly. The pressure gradient and entrainment of vortexes are main reasons that synthetic jet actuator controls low speed primary jet direction.
