Abstract

In the present study, 2D numerical simulation of flow around a Circular cylinder and the effect of Plasma actuators to control the flow around it have been investigated. Plasma actuators which have been used include single plasma actuator and Linear Plasma Synthetic Jet Actuator (L-PSJA). In order to numerically simulate the actuators, the Linearized force model has been used. In the present work, accuracy of the Linearized force model to analysis the Plasma actuators behavior and the effect of their position on the point of separation and elimination of the vortices have been investigated. The results show that the simulation of actuators operates qualitatively successful in flow separation using Linearized force model (despite of its simplicity). Using of single Plasma actuators at angle of ± 45 and ± 90 degree is the best position of the Plasma actuators. The position of the actuators at angel of ± 90 degree is recommended, if the lower power consumption of the plasma and at the same time the most influence on the flow is to be considered. Using L-PSJ actuators at angel of ± 45 degree is not recommended, due to low influence on the flow and higher power consumption.
