Abstract: The effects of inlet airflow velocity and notch width on the velocity field and lint cleaner pressure field were simulated using the CFD (computational fluid dynamics). The velocity vector was applied to analyze the effect of inlet airflow velocity. The lint cleaner can run normally with velocity of 15m/s, which is easy blocked at higher and lower velocity. The pressure field contour and pressure distribution analysis were used to study the effect of notch width. Under 20mm notch width and 15m/s inlet airflow, no exhaust air phenomenon in lint cleaner while it has the lowest supplement air velocity, the best cleaning rate and loss lint rate. The CFD simulation results are consist to that of the experiment, indicating that the CFD analysis can optimize the operating parameters for the flow-through air lint cleaner.
