OPTIMIZING THE UNIT STRUCTURE OF THE DRAINAGE-TYPE CYCLONE SEPARATOR FOR SAND SAMPLE COLLECTION

This paper introduces a cyclone separation sand sampler with diversion flow to enhance soil wind erosion monitoring accuracy. Using CFD simulations and orthogonal testing, the optimal structural parameters for improved sampling efficiency were determined. A response model showed strong predictive capability with a P-value less than 0.0001 and R² of 0.9482. Wind tunnel tests demonstrated that the new sampler achieved a 91.44% efficiency, surpassing the 90.81% of the traditional design. The research provides valuable data for more accurate wind-sand flow monitoring, aiding in desertification prevention and improving wind erosion assessments in grasslands.
