Turbulent jet, which is used in many industrial processes like heat transfer, admixture and reaction promotion, is studied to find a method of control. It has been reported that the control of opposed jet has the critical factor in the jet center. And, we try to examine the control method of the fluidic actuator by very small signals, for example, laser radiation pressure in axisymmetric flow fields. In this study, investigate role of thin cylinder around the jet center and discuss shift of the impact position by laser radiation pressure in the jet center in the opposed jets.
