Effects of wind direction, wind speed and travel speed on spray deposition

Pesticide Science, 1993
AbstractDeposition variability from a conventional field sprayer, and effects of wind and travel speed were measured by collecting on small artificial targets in the swath. Whilst deposition on 0.1‐m2 plots varied by a factor of 3, deposition on single vertical targets typically varied by a factor of 10 and on horizontal targets by a factor of 6 ...

Multi-step wind speed forecasting based on hybrid multi-stage decomposition model and long short-term memory neural network

Energy Conversion and Management, 2020
The intermittent nature of wind can represent an obstacle to get reliable wind speed forecasting, thus many methods were developed to improve the accuracy, due to unstable behavior patterns and the presence of noise signal.

Short-term wind speed forecasting based on the Jaya-SVM model

International Journal of Electrical Power & Energy Systems, 2020
Wind energy is an emerging environmentally friendly energy source. However, due to the uncertainty and volatility of wind speed, wind energy cannot be effectively exploited, and it is essential to build an accurate wind speed forecasting model.

HIGH WIND SPEED REGIME

2006
Under high wind speed conditions breaking waves disrupt the air-sea interface producing a two-phase zone—air bubbles in water and sea spray in air. This mixed-phase environment changes the regime of air-sea interaction. In this chapter, after reviewing dynamics of air-bubbles and sea spray droplets in detail, the reader is exposed to the idea that ...

Wind Power Plants Operation at Variable Wind Speeds

2020 IEEE 14th International Symposium on Applied Computational Intelligence and Informatics (SACI), 2020
The purpose of the present paper is to build a driving algorithm ensuring, from the point of view of the captured wind energy, the wind turbine’s operation within the optimum area, based on the measurements of the wind speed. The optimum values of the permanent magnet synchronous generator’s (PMSG) delivered power are determined based on the kinetic ...

Equivalent Speed and Equivalent Power of the Wind Systems that Works at Variable Wind Speed

2015
This paper presents an analysis of the dynamics of the wind systems that work at variable wind speeds. This analysis is based on numerical simulations that use the motion equation. In this paper, usual mathematical models of both wind turbine and permanent magnet synchronous generator are used. Based on the measurements of both wind speed and generator
