DYNAMICS OF LIQUID FILLED SHELL: NON-CYLINDRICAL CAVITY

Open Access

Abstract

A theory is presented for the approximate computation of eigen- frequencies of liquid oscillations in non-cylindrical cavities. The eigen- frequencies are essential for the prediction of stability of liquid-filled shell. The theory reduces the problem of finding the eigen value to a simple integration which can be performed by hand computation when the shape of the cavity is known. Comparison of theoretical prediction and available experimental data shows very good agreement.
