| Abstract: | In order to study the control effect of plasma excitation on the separated flow field of a slender body at high angles of attack, a phenomenological model is used to simulate the effect of plasma excitation, and the control effect of plasma on the flow is simplified as the energy injection into the flow field. The influence of plasma discharge energy density and discharge position on the control effect is studied by numerical simulation. The results show that the back vortex structure of the slender body can be controlled by applying plasma excitation at the head of the slender body, and then the lateral force generated by the slender body at high angles of attack can be controlled. When the plasma excitation position is constant, the larger the discharge power is, the greater the influence on the separation flow field of the slender body at high angle of attack is; When the plasma excitation is far away from the head, the control effect on the separation flow field of the slender body is weaker; When the plasma excitation is on the same side of the low vortex and far away from the symmetrical surface of the windward surface, the separation flow field of the slender body can be controlled. |
