摘要：
The small amplitude sloshing of an ideal fluid in a rectangular rigid aqueduct with a rigid baffle was studied. The complicated fluid domain caused by the baffle was divided into several sub-domains with simple shape and uniform boundary conditions. The velocity potential functions corresponding to each fluid sub-domain were studied. The general expressions for the modal shape functions of sub-domains were analytically deduced by using the method of separation of variables based on the superposition principle. According to the continuous conditions of velocity and pressure at the interface between two sub-domains and the free fluid surface wave conditions, the unknown coefficients in the velocity potential solutions were uniquely obtained. The natural sloshing frequencies and modal functions were numerically determined by using the Fourier series expansion. © 2016, Editorial Office of Journal of Vibration and Shock. All right reserved.
