Recently sloshing with various flow patterns has been attracting much attention particularly in conjunction with the integrity of fast breeder reactors. In the present paper, theoretical and experimental study was performed to investigate nonlinearity of sloshing with circulating flow in a rectangular tank subjected to horizontal excitations. It had been found that the nonlinearity of sloshing is affected by the water depth and the flow velocities. In the theoretical calculation assuming that the horizontal surface flow instead of circulating flow was dominant in the tank, we conducted potential flow analysis based on the superposition of the velocity potential of noncirculating flow and that of the surface flow. In this paper, the actual surface velocities were measured with a Pitot tube and those were employed in the calculation, which gives better agreement.
