We investigate the effect of inertial particles dispersed in a circular patch finite radius on stability two-dimensional Rankine vortex semi-dilute dusty flows. Unlike particle-free case where no unstable modes exist, we show that feedback force from triggers novel instability. The mechanisms driving instability are characterized using linear analysis for weakly and further validated against Eu...

The first true common volume observations of the PMSE source region with 4 radars are presented in this paper. Radar frequencies 8, 56, 224, and 930 MHz used study. Three days experimental at EISCAT presented. Numerical simulations mesospheric dusty/ice plasma associated observed radar effect neutral air turbulence on generation strength density perturbations using four presence various dust pa...

We study in details a pumping mechanism for the λ = 1.35 cm maser transition 616 → 523 in ortho-H2O based on the difference between gas and dust temperatures. The upper maser level is populated radiatively through 414 → 505 and 505 → 616 transitions. The heat sink is realized by absorbing the 45 μm photons, corresponding to the 523 → 414 transition, by cold dust. We compute the inversion of mas...

It is shown that inhomogeneous heating of the dust grain by ion flow in a glow discharge results in a photophoresislike force. According to our estimations, this radiometric force can be comparably-valued with the ion-drag force under the conditions of microgravity dusty plasma experiments.
