Attitude Control of Aircraft Using Only Synthetic Jet Actuators When Stall Occurs
IEEE Access, 2018 This paper proposes a novel active flow control method for a special aircraft, that using only synthetic jet actuators (SJAs) to achieve pitch-roll-yaw attitude control at a high angle of attack when the stall occurs.

Advanced Theory and Simulations, EarlyView.Computational fluid dynamics analyses assess the upstream locomotion performance of anisotropic microrollers with varying height‐to‐width ratios. Observing their successful upstream locomotion in veins, their performance in hepatic circulation is investigated for treating primary liver cancer.

Poynting's theorem in magnetic turbulence [PDF]
arXiv, 2017 Poynting's theorem is used to obtain an expression for the turbulent power-spectral density as function of frequency and wavenumber in low-frequency magnetic turbulence. No reference is made to Elsasser variables as is usually done in magnetohydrodynamic turbulence mixing mechanical and electromagnetic turbulence.

Advanced Theory and Simulations, EarlyView.Increasing half‐cycles intensifies turbulence due to enhanced vortex interactions and flow separation at the diverged‐outlets. Longer wavy ducts are shown to increase flow acceleration, resulting in greater output velocities and more turbulent‐kinetic‐energy production. Wave‐period plays a crucial role in determining turbulent intensity, with amplitude

, 2009 Ce document est une synthèse de mes travaux de recherche en Physique qui s'articule selon trois axes: turbulence hydrodynamique, magnétohydrodynamique et turbulence d'onde. J'ai développé des techniques de mesure originales destinées à l'analyse lagrangienne de la turbulence hydrodynamique: il s'agit de suivre le mouvement de particules entraînées par ...
