Experiment and numerical simulation of pressure field for water cushion belt conveyor
Abstract：Reynolds equation of water cushion was deduced from Navier-Stokes equation. The pressure flied of water cushion was numerical calculated by the CFD software under different conditions. Results of numerical simulation show that hydrostatic which caused by muzzles is the main part of the load capacity of the water film. The pressure of water film is bigger with bigger muzzles diameter. The arrangement of the muzzles influence the pressure flied distribution of water film. Staggered arrangement of muzzles can increase the pressure and carrying capacity of conveyor. The number of muzzles rows and lines influence the pressure and stability of water film. Presented the experiment facility of the wa- ter cushion belt conveyor, the experimental study on the facility was carried out to measure the pressure distribution of the water film under the same muzzles diameter and arrangement. Comparison of the computational results with the ex- perimental data show that numerical results basically indicate the flow features of the water cushion and can provide the theoretic evaluation to improve the air-cushion design.
