In the last decade, unmanned aerial vehicle (UAV) sprayers have been growing rapidly worldwide as a new method for pesticide application, especially in Asian countries. More and more manufacturers service providers are currently aiming at UAV spraying operation fruit trees with higher economic value. We evaluated spray performance of an electric six-rotor sprayer using orchard mode (different application volumes flight patterns) hilly apple small sparse (SS) plain tall-spindle...
Accurate measurement of the downwash flow field plant protection unmanned aerial vehicles (UAVs) is essential for analyzing spatial distribution droplets. To realize on-line rapid detection a multi-rotor UAV, flexible polypropylene device based on principle full bridge strain effect was proposed. Its performance physical deformation caused by wind pressure. The Fluid Flow and Static Structural modules ANSYS 16.0 finite element software were used to simulate one-way fluid-solid coupling...
Motion of particles in two-phase flow between two rotary pads is simulated with coupled lattice Boltzmann method (LBM) and discrete element (DEM), which the LBM used for calculating fluid flow, while DEM accounting interaction moving particles, both are constructed by 'boundary' LBM. Numerically, field on down-pad simulated, vortexes found; Pressure maps observed different pad angle velocities; Finally motion investigated, our results show that most get out interlayer at nearly same place,...
Abstract Permeability is one of the most important characteristics hydrocarbon-bearing formations. Many approaches exist for estimating permeability. Formation permeability often measured in laboratory from core samples or evaluated well test data. However, analysis and data are expensive available only a limited number wells field. On other hand, logging almost all wells. Therefore, accurate prediction formation using becomes very attractive. This paper describes unique integrated modeling...
Square shell is one structural type which quite common to be seen in engineering. This paper focuses on the carrying capacity of square shell, and studies influence round radius thickness ratio mass external volume load factor under linear buckleing shell. Numerical results show that, With increase radius, will first decrease, then approach that circular while also increase. thickness, ration rapidly help better design pressure hull submarines.
Multiblade centrifugal fans are widely used in various fields. With the rapid increase fan performance requirements, improving aerodynamic and reducing noise by modifying individual component parameters no longer sufficient to meet demands of actual engineering applications. In this work, a combined reduction scheme was adopted reduce level under different operating conditions while its performance. The three-dimensional unsteady flow acoustic field were calculated simultaneously via direct...
The accurate setting of input parameters in the numerical simulation downwash airflow from a UAV sprayer is important for acceptable results. To provide real data (rotor speed and pitch angle) airflow, wireless parameter measurement system (WSPM-System) was designed tested this study. consists hardware software based on Arduino LabVIEW, respectively. Wireless communication realized by nRF24L01. lattice Boltzmann method (LBM) applied airflow. results showed that valid distance WSPM-System 100...
It is of great significance to investigate the rising behavior a bubble in immiscible fluids chemical and metallurgical engineering. A 3-D model established free-floating single (water-heavier liquid biodiesel-lighter liquid) numerically simulated by phase-field method. After fluctuation certain distance, tends be stable. takes more time for larger reach stable shape than smaller one. The terminal aspect ratio bubble, ET, with same size heavier that lighter liquid. With increase size, ET...

It is well known that the number of particles should be scaled up to enable industrial scale simulation. The calculations are more computationally intensive when motion surrounding fluid considered. Besides advances in computer hardware and numerical algorithms, coupling scheme also plays an important role on computational efficiency. In this study, a particle immersed boundary method (PIBM) for simulating fluid-particle multiphase flow was presented assessed both two- three-dimensional...
