The aeroacoustic fields of twin jets and the equivalent single jet were experimentally investigated using particle image velocimetry (PIV), schlieren visualization, acoustic measurement. present study focuses on jets, effect interaction between each was various nozzle spacing. PIV results indicated that strong causes elliptical growth a cross-stream plane decrease in Reynolds stress inner shear...

The nonlinear dynamics of uncharged ideally polarizable spheres freely suspended in a viscous electrolyte in a uniform electric field are analysed using theory and numerical simulations. When a sphere polarizes under the action of the field, it acquires a non-uniform surface charge, which results in an electro-osmotic flow near its surface that scales quadratically with the applied field magnit...

In this paper we introduce the notion of scale pressure and measure theoretic for amenable group actions. A variational principle actions is presented. We also describe these quantities by pseudo-orbits. Moreover, prove that if $ G a finitely generated countable discrete group, then coincides with respect to
