Nonlinear sloshing analysis of liquid in tanks with arbitrary geometries
A method is newly proposed for calculating the nonlinear dynamic behavior of liquid in tanks with arbitrary geometries. The formulation uses the orthogonality of the linear mode shapes and the numerical perturbation technique. The problem is reduced to the nonlinear coupled ordinary differential quations describing the timewise trend. Numerical examples carried out on the sloshing in rectangular and axisymmetric tanks demonstrate the versatility of the present method.
