Based on the hydraulic model test of an oblique inlet passage, the hydraulic loss coefficient and distribution of the outlet velocity of the inlet passage are obtained in the paper.
The oblique and multi directional waves are usually generated by serpent type wavemakers in laboratory basins. But there are these is the limited test area.
