A Binary Integer Programming Method for Optimal Wind Turbines Allocation
Clean Technologies, 2021 The present study introduces a Binary Integer Programming (BIP) method to minimize the number of wind turbines needed to be installed in a wind farm. The locations of wind turbines are selected in a virtual grid which is constructed considering a minimum

Reflected Protons in the Lunar Wake and Their Effects on Wake Potentials
Journal of Geophysical Research: Space Physics, 2020 AbstractThe refilling of the lunar wake is facilitated by the wake ambipolar electric potential arising from the electron pressure gradient. Incident solar wind protons can be reflected by the lunar crustal magnetic fields and the lunar surface on the dayside and repicked up, entering the lunar wake due to their large gyroradii.

Inlet Guide Vane Wakes, Including Rotor Effects [PDF]
Volume 1: Turbomachinery, 1995 A series of fundamental experiments are directed at the acquisition and analysis of data defining forcing functions generated by an inlet guide vane (IGV) row, including interactions with the downstream rotor, for application to turbomachine forced response design systems. The research fan facility is comprised of an IGV row upstream of a rotor.
