Description
Summary:Complex variable methods have been devised to investigate the effect of geometric irregularities on the dynamic characteristics of inviscid liquids in circular basins. The fundamental frequency of the slosh mode has been determined by the stationary property of Schwarz quotients. Lower and upper bounds for the frequency have been obtained by a comparison theorem. Results show that frequencies are decreased with the increase of out of roundness parameters.
