基于Fluent的小型扫路机内部流场数值分析及优化
Numerical Analysis and Optimization of the Internal Flow Field in a Small Sweeper Based on Fluent
摘要
Abstract
To address the challenge of mesh plates clogging within the small sweeper casing,the computational fluid dynamics(CFD)method based on fluent is employed to simulate the flow field inside the sweeper casing.The Realizable k-ε turbulence model and the multiple reference frames(MRF)approach are utilized for the simulation.The impact of the number of mesh holes on the fan intake mesh plate and the height of the fan intake chamber on system performance are analyzed.The simulation results show that the reason why the mesh plate inside the sweeping machine case is prone to blockage is due to the small height of the air intake chamber of the fan,which leads to high flow velocity at the mesh hole and easy adsorption of garbage on the mesh plate,thereby affecting the smoothness of the fan air intake and reducing the performance of the entire system,and simply increasing the number of mesh holes on the intake mesh plate of the fan cannot significantly improve the operational performance of the pneumatic system of the sweeper.By optimizing critical parameters such as the distance of the fan intake chamber,the calculations demonstrate that the fan power can be increased by 6.94%,the fan flow rate can be elevated by 6.27%,and the suction pressure at the nozzle can be boosted by 10.15%.Consequently,the performance of the entire pneumatic system is significantly enhanced.关键词
