Iran is one of the world's arid regions and exposed to dust particles in the air. This is important in spatial and temporal terms as well as the affects human health. In this paper a day when due to the amount of dust particles visibility reduces to 5,000 m is considered the dusty day. In the spatial and temporal analysis of dusty days 38 synoptic stations were studied. In order to conduct data...

This study attempts to analyze the effect of diverse parameters peristaltic flow second grade dusty fluid through a curved configuration. Stream function conversions are used model separate system equations for dust particles and fluid. The Perturbation technique is get analytical solutions results verified graphs. It noticeable that trapped bolus, compresses both with an increase in `the param...

Pinned solitons are a special class of nonlinear solutions created by supersonically moving object in fluid. They move with the same velocity as and thereby remain pinned to object. A well known hydrodynamical phenomenon, they have been shown exist numerical simulation studies but date not observed experimentally plasma. In this paper we report first experimental excitation dusty (complex) plas...

The DuEl (Dust-Electron) device, a modified Penning-Malmberg trap for the confinement of dust-contaminated electron plasmas, is currently under construction at the University of Milano with the aim of investigating the dynamics of magnetized complex (dusty) electron plasmas [1]. The overall behaviour of such plasmas is heavily affected by the addition of a small fraction of micrometric or sub-m...

The purpose of the present paper is to study an unsteady laminar flow of an incompressible conducting viscous dusty fluid between two infinitely non-conducting parallel plates, where above plate is bounded by porous medium. The flow is influenced by pulsatile pressure gradient, uniform magnetic field which is applied perpendicular to the plates and due to oscillations of the plates under the ef...
