SOME STUDIES OF A FLOATING LID TYPE DEVICE FOR SUPPRESSION OF LIQUID SLOSHING IN RIGID CYLINDRICAL TANKS

Abstract

Floating lid type devices having a diameter of 85%, or more, of the tank diameter are quite effective in providing increased damping of the peak total force response. A 67% lid provides almost no damping at all. The peak force responses with the 85% lid decreased with increasing excitation amplitude, but increase slightly with increasing equivalent Reynolds' number of the test liquid. This is accompanied by a pronounced increase in the liquid first mode resonant frequency. The forces acting directly on the lids appeared to be rather large so that such devices may well prove to involve significant weight penalties for the damping provided.
