摘　　要：对摘得的花生荚果进行清选是花生收获机的主要功能之一。为了研究清选过程中流场的影响和规律,运用Fluent中的DPM模型对花生清选室气流场进行了数值模拟,针对显著影响气流场分布的主要参数按三因素三水平安排试验,得出了不同参数组合下气流场的分布规律和花生物料群迹线图,为花生收获机清选装置的设计提供参考。Cleaning after fruit picking is one of the main functions of the peanut harvester.In order to study the impact and rule of the flow field in the cleaning process,the DPM model in Fluent was used to conduct numerical simulation about the airflow field in peanut cleaning chamber.Tests of three factors and three levels were arranged according to main parameters significantly affecting the distribution of airflow field.Airflow field distribution under different groups of parameters and the trajectory plots of peanut mixtures were obtained.These results provided references for the design of peanut cleaning device.
