We have performed particle-resolved direct numerical simulations of many heavy non-spherical particles settling under gravity in the dilute regime. The are oblate spheroids aspect ratio $1.5$ and density . Two Galileo numbers considered, namely $111$ $152$ , for which a single spheroid follows steady vertical oblique path, respectively. In both cases, strongly inhomogeneous spatial distribution...

Abstract The triaxial attitude control of the tailless aircraft depends heavily on effectiveness actuators. Still, actuators have redundancy characteristics, cross-coupling rudder effect, and so on. Therefore, reconfigurable allocation under typical actuator faults is deeply studied in this paper. rationality incremental method based quadratic programming are thoroughly verified for application...

Three-dimensional flows over impulsively translated low-aspect-ratio flat plates are investigated for Reynolds numbers of 300 and 500, with a focus on the unsteady vortex dynamics at post-stall angles of attack. Numerical simulations, validated by an oil tow-tank experiment, are performed to study the influence of aspect ratio, angle of attack and planform geometry on the wake vortices and the ...
