回転翼UAVによる人工授粉噴霧器内の花粉模擬粒子流動解析

抄録

The spray injection of lycopodium powder, which simulates apple pollen, was numerically simulated with a Lagrangian discrete phase model (DPM) to design a rotary-wing type UAV for the artificial pollination of apples. The lycopodium powder stored in a powder tank was suctioned by airflow through an inner air nozzle and injected through the injection nozzle. The computed results showed a good agreement with the injection experiments in terms of spray foam. However, further investigation was required on the flow rate of the powder and unsteady spray foam variation.
