The Airflow Field Characteristics of UAV Flight in a Greenhouse

The downwash airflow field of UAVs is insufficient under the dual influence greenhouse structure and crop occlusion, distribution characteristics flight flow in greenhouses are unclear. In order to promote application greenhouses, a were studied herein. containing tomato plants, porous media model was used simulate obstacle effect crops on airflow. multi-reference system method selected solve UAV. Studies have shown that generated by UAV mainly affected structure. With increase height, ground weakened, spread downward around. area became larger, while development convection less affected. simulation verified experiments, linear regression analysis carried out between experimental value value. results found be good agreement with results.
