Numerical simulation of flow fields of synthetic jet and across primary jet

Modeling a blowing/suction type boundary for synthetic jet actuator,it considers the actuator cavity,exit nozzle and exterior flow field as a single computational region.Then the vectoring angle of the across primary jet and the different pressure on each wall are discussed.It shows that the vectoring angle of the across primary jet is affected mainly by the locations of actuator,and in the primary jet channels the pressure difference on the walls between actuator and exit of primary jet is especially great.The synthetic jet's effect on primary jet under different mode is discussed in the paper.
