基于Fluent的重载植保无人机雾滴沉积特性的研究
Research on Droplet Deposition Characteristics of Large-load Plant Protection UAV Based on Fluent
摘要
Abstract
Taking the FBH-300T tandem heavy-duty oil-powered dual-rotor UAV with a payload of 135kg as the re-search object,the wind field and nozzle data of the aircraft rotor were measured,and the simulation model of the nozzle in the external flow field was established using Fluent,and computational fluid dynamics was used.The effects of FBH-300T UAV flight speed,crosswind and load on droplet deposition during aircraft application were simulated and verified by the method of Computer Fluid Dynamic.The results show that the flight speed,crosswind and load of the plant protec-tion UAV will affect the deposition distribution of droplets.The droplet deposition is most affected by the crosswind,fol-lowed by the flight speed,which is least affected by the load.In the crosswind of/s and the flight speed range of 0-5m/s,the penetration and drift of the droplets do not change much.Consistent with the results of field experiments.It is proved that it is feasible to use Fluent to carry out research on droplet deposition characteristics of plant protection drones.This paper can provide a reference for the research on droplet drift,movement and deposition of plant protection drones.关键词
