Numerical simulation of the effect of air hole distribution on the performance of air cushion belt conveyors
The application of air cushion belt conveyor in coal conveying system can improve the safety and stability of coal conveying,and the way of air hole distribution has a significant impact on the conveyor performance.In this study,a numerical simulation analysis was carried out for an air cushion belt conveyor with a complete double arc air chamber.The simulation used an advanced size-adaptive model,dynamic mesh technique and 6-degree-of-freedom model to predict the lifting process of the conveyor belt and material under the action of the air film.The accuracy of the numerical simulation was verified by comparing with the experimental data.By further simula-ting the working conditions with different types of air holes arrangements,the study obtained the flow field characteristics and pressure distribution characteristics inside the air film of the conveyor.When the air holes arrangement is staggered,the air consumption of the conveyor is less and the pressure distribution inside the air film is more uniform.The research results are of great significance for the further optimization design of air cushion belt conveyors.
