DESCRIPTORS Liquid rocket propellants in Propellant tanks, Motion, Rotation, Vortices, Dynamics, Drainage, Fluid flow, Test, Theory. Fuel tanks, Configuration, Design. Identifiers Sloshing. Experimental and theoretical studies were performed on vortex formation while draining fluid from cylindrical tanks, and related liquid dynamic behavior. The experimental studies are largely visual, through motion picture films, but even so reveal many interesting details of vortex formation and behavior, and also include some data on time required for draining with various fluids, tank bottom shapes, and slosh and vortex suppression devices. An analytical study of vortex formation in cylindrical tanks is also presented in an attempt to understand and delineate better the flow mechanisms involved. Author
