摘　　要：以气吸式垂直圆盘排种器为研究对象,对气室流场和种子运动过程进行了分析,利用FLUENT软件建立了气吸式水稻芽种排种器充种过程的仿真模型,并对水稻芽种在充种过程中的速度场、压力场和种子的吸附轨迹及种子的吸附速度进行了模拟。结果表明:利用FLUENT软件对气吸式水稻芽种排种器充种过程进行仿真是可行的,数值模拟结果与试验结果吻合较好。Using the Air vertical-rotor Seed-metering Device （ASD） as the investigation object, gas field and seed sporting process were analyzed, and seed-filling process of ASD through FLUENT software was modeled. Then simulated air speed, air pressure, seed trajectory and seed sporting speed were simulated in the seed-filling process of rice bud-sowing. The results showed that it was feasible to simulate the seed- filling process of the Air vertical-rotor seed-metering device by FLUENT software, numerical simulation results were in good agreement with the experimental results.
