The experiment facility of the multi-passage air-cushion platform is presented. The experimental study on multi-passages air-cushion platform is carried out to measure the pressure distribution of the air flow inside. Commercial CFD software PHOENICS is employed to simulate the same flow field. Comparison of the computational results with the experimental data shows that numerical results basically indicate the flow features of the air-cushion and can provide the theoretic evaluation to improve the air-cushion design.
