摘　　要：为深入研究联合收割机风筛选装置气流场的分布规律,改善其清选质量,利用CFD软件Fluent对其气流场进行数值模拟分析。得到了在单风口无导风板、单风口加装导风板以及双风口加装导风板三种工况下清选室内气流速度云图,并进行对比分析。为联合收割机风筛选装置的进一步设计改进提供可靠的理论依据。This is in order to further study the distribution of airflow field of the wind screening device and improve its selecting effect. The airflow ve- locity contours of the cleaning room were obtained under three working conditions which are single tuyere without reflector, single tuyere with reflec- tor, double tuyere with reflector. The comparison and analysis of these provide a reliable theoretical basis for the further design and improvement of the wind screening device.
