摘      要：An analytical procedure is presented to evaluate the fluid sloshing characteristics in a two-dimensional(2D)rectangular container with a bottom-mounted T-shaped *** fluid region is divided into several sub-domains with hypothetical interfaces and the velocities and pressures of the fluid on adjacent interfaces should be *** separation of variables in conjunction with the superposition principle is employed to formulate the velocity potential of each *** Fourier series expansion is used to derive the eigenvalue equation by substituting the velocity potential solutions into the free surface conditions and the continuity conditions on adjacent *** the horizontal base excitation,the total velocity potential of fluid is decomposed of the impulsive and perturbed velocity *** orthogonality of the sloshing modes is demonstrated by implementing Gauss *** dynamic response equation is established by incorporating the total velocity potential solution into the surface wave *** agreements are achieved between the present results and those from the reported literature and finite element *** results are exhibited to reveal the effect of the baffle parameters and excitation frequency on sloshing characteristics and responses of liquid.
