Abstract:

The pressures measured at the walls of an oscillating, cylindrical tank partly filled with a liquid may be disturbed by the presence of stiffener rings. In order to gain an insight into the character of such disturbances, an approximate theory was developed that corrects the smooth wall solution of the oscillating tank for the effects of horizontal rings. The theory is valid for rings whose width is small as compared to the tank radius. Equations are dderived describing the effect of a single, flat ring. However, the theory can be extended to cover any number and crosssection of rings. Numerical calculations were carried out for a tank and pressure pick-up configuration tested at ABMA and intended for use on flying missiles. Though the pressure disturbances extend over the whole height of the liquid in the tank, they are sizable only in the neighborhood of the stiffener ring, and become negligible about two ring widths off the ring.
