Abstract:

Experimental techniques were developed for measuring slosh damping in a variety of tank and baffle configurations. The various methods were compared and shown to be in satisfactory agreement. The Able-Star damping investigation made use of one of the methods having the broadest application possibilities. A systematic variation of tank shape parameters is continuing in support of ballistic missile programs like ATLAS, TITAN, and THOR, and in preparation for the needs of future space explorations systems. Nonlinear damping effects were investigated. Waves sweeping across a domed tank bottom resulted in plunging flow with high but erratic damping. Waves splashing against damping rings were quickly damped, but a new slosh mode persisted with low damping.
