This paper presents a method to design the optimum shape of a container and the appropriate velocity pattern considering the damping of sloshing for liquid container transfer. The sloshing phenomenon is numerically analyzed by a boundary element method (BEM). For transfers using conventional trapezoidal velocity patterns, the optimum container shape is designed through BEM simulation for various slope angles of the side or bottom wall of the container. In terms of genetic algorithm which is a well-known approach for global optimization, the optimum shape of the container was obtained by maximizing the performance index considering the resonant frequency of first-mode sloshing, the volume of liquid and the slope angle of the side wall. In addition, it was shown that residual sloshing was effectively suppressed by adjusting the acceleration (deceleration) time of container transfer to the period of first-mode sloshing.
