Abstract : In the study of vortex flow in a confined vortex system, such as a colloidal core nuclear reactor prototype, an apparatus is needed for the rapid injection and removal of particles, parallel to the flow, while the system is in the run mode. The apparatus must be such that it will cause minimum flow perturbations in the vortex system. According to this invention, a three way valve system is provided in one of the gas injector control vanes of a confined vortex system. In the injection mode of the system, the valve has a lip which is turned to direct the particles in the direction of flow within the chamber. In the exhaust mode, the valve has a lip which is positioned to intercept the particles moving in the flow in the vortex chamber. In the run mode the valve is turned to provide a smooth contour with no protrusions into the flow.
