The Numerical Simulation of Swirling Airflow Field for Different Swirling Airflow Head in Swirling Airflow Finishing

The key of swirling airflow finishing is how to generate the swirling airflow. In the paper, three swirling airflow head are discussed according the manners of tangential inflow. By means of FLUENT, the general software of CFD, the swirling airflow field from different airflow head is simulated. The simulation results are shown by the flow line graphs, tangential velocity, radial distribution graphs, etc. All we have studied is as the basis for the determination of the application scope of each swirling airflow head.
