Transition and separation are difficult but important problems in the field of fluid mechanics. Hitherto, transition have not been described accurately mathematical terms, leading to design errors prediction machine engineering. The nonlinear uncertainty involved makes it analyze these phenomena using experimental methods. Thus, new ideas methods required for transition. In this article, after ...

A novel adaptive method to achieve both path following and formation moving along desired orbits in the presence of a spatio-temporal flowfield is presented. The general flow with unknown time-varying parameters. so-called \emph{congelation variables} used estimate parameters, which do not have any restrictions on rate their variation. asymptotic properties resulting system are studied detail. ...

The study of unsteady aerodynamic phenomena in wind tunnels is supported by gust-generating devices capable generating adjustable magnitude and periodicity velocity fluctuations a flowfield. Gusts are typically generated actively introducing moving vanes to direct the flow, or passively tailoring boundary layer growth shape tunnel. flow facility used here student-built closed-return low-speed t...

We present an analysis of the flowfield inside a novel crossflow microfiltration device. The filter performance relies on shear focusing by means of a corrugated channel. The flow and shear stress characteristics inside the filter are studied by means of both micro Particle Image Velocimetry (micro-PIV) measurements and Computational Fluid Dynamics (CFD) analysis. We show that an increase of th...
