| Abstract: | In order to improve the cleaning quality of air-and-screen cleaning device for combine harvester, its airflow field of the vibration sieve is researched. A method for hydrokinetics simulation and analysis is presented by using ANSYS/FLOTRAN CFD. Then, this paper discusses how to build simulation model and analyze the analysis results. At last, taking the airflow field in air-and-screen cleaning device for combine harvester as an instance, the ideal airflow field distribution is obtained, which shows the validity and superiority of this simulation and analysis method. |
