| Abstract: | A boundary element algorithm has been set up to solve the axisymmetric and any m-orderedasymmetric slosh of liquid in a spinning tank in normal gravity conditions. Two kinds of harmonicfunctions have been introduced to determine the principal diagonal elements of BEM coefficient ma-trix. One examination technique has been sugsested here to test the computer code and estimate the ap-proxunate degree of the numerical solution. |
