A magnetohydrodynamic (MHD) shock front can be unstable to the corrugation instability, which causes a perturbed become increasingly corrugated with time. An ideal MHD parallel (where velocity and magnetic fields are aligned) is unconditionally whereas hydrodynamic (HD) counterpart stable. For partially ionised medium (for example solar chromosphere), both species coexist stability of system ha...

Partially ionized plasmas (PIP) are essential constituents of many astrophysical environments, including the solar atmosphere, interstellar medium, molecular clouds, accretion disks, planet ionospheres, cometary tails, etc., where ionization degree may vary from very weak to almost full ionization. The dynamics PIP is heavily affected by interactions between various charged and neutral species ...

this study investigates natural frequency analysis of an fg composite rectangular plate partially contacting with a bounded fluid. the material properties are assumed to be varying continuously through the thickness direction according to a simple power law distribution in terms of volume fraction of material constituents. wet dynamic transverse displacements of the plate are approximated by a ...

Based on a non classical plate theory, an analytical model is proposed for the first time to analyze free vibration problem of partially cracked thin isotropic submerged plate in the presence of thermal environment. The governing equation for the cracked plate is derived using the Kirchhoff’s thin plate theory and the modified couple stress theory. The crack terms are formulated using simplifie...

in this paper, fluid flow between two parallel flat plates that are partially filled with two-dimension porous media is investigated numerically using single relaxation time (srt) lattice boltzmann method (lbm) at pore scale. the considered obstacles are random, circular, rigid and granular with uniform diameters. single component and single-phase viscous newtonian fluid are considered as worki...

OBJECTIVE To examine the demographic and radiographic features of patients with spontaneous cerebrospinal fluid otorrhea and to determine whether they display similar characteristics to patients with idiopathic intracranial hypertension. STUDY DESIGN Retrospective case review. SETTING Academic, tertiary referral center. PATIENTS All individuals presenting with spontaneous cerebrospinal fl...
