Passive wake flow control of vertical axis wind turbines in array configurations by Jun-Kai Duan, Zi-Kang Wang, Hai-Ping Tian, Rui-Xue Feng, Wen-Bo Yao, Guo-Zhen Ma

“…This study introduces a passive wake control strategy for vertical axis wind turbine (VAWT) arrays using arc-shaped deflectors. Unlike prior works focusing solely on layout or blade optimization, this research systematically explores the effects of deflector position, orientation, and spacing on wake interaction and power output through two-dimensional CFD simulations. …”

Performance enhancement of cross-axis-wind-turbine: Design and CFD analysis of an omni-directional flow concentrator by Christopher Clement Rusli, Keen Kuan Kong, Shin Yee Khoo, Su Xian Long, Wen Tong Chong

“…Results demonstrate that the ODFC redirects wind vertically at 67.17–76.33 % of initial speed, improving upon the flat plate deflector by 50.66 %. Prototype fabrication and experimental validation confirmed these findings. …”

Pre-flight performance of the ion energy mass spectrum analyzer for the Martian Moons eXploration (MMX) mission by Shoichiro Yokota, Ayako Matsuoka, Naofumi Murata, Yoshifumi Saito, Kazushi Asamura, Satoshi Kasahara, Dominique Delcourt, Lina Z. Hadid, Naoki Terada, Kunihiro Keika, Yuki Harada, Hiromu Nakagawa, Kei Masunaga, Shotaro Sakai, Yoshifumi Futaana, Shun Imajo, Kanako Seki, Masaki N. Nishino, Yuki Kitamura

“…The hemispheric field-of-view (FOV) is acquired by a pair of angular scanning deflectors, and the energy/charge and mass/charge are determined for each ion by an electrostatic analyzer and a linear-electric-field (LEF) time-of-flight (TOF) analyzer, respectively, with an enhanced mass resolution of $$m/\Delta m\sim 100$$ m / Δ m ∼ 100 . …”
