The evolution of internal solitary waves (ISWs) propagating in a rotating channel is studied numerically in the framework of a fully-nonlinear, nonhydrostatic numerical model. The aim of modelling efforts was the investigation of strongly-nonlinear effects, which are beyond the applicability of weakly nonlinear theories. Results reveal that small-amplitude waves and sufficiently strong ISWs evo...

The field of fluid mechanics was further explored through the use a particle-in-cell model for mathematical study Stokes axisymmetric flow swarm erythrocytes in small vessel. were modeled as inverted prolate spheroids encompassed by fictitious envelope. fourth order partial differential equation governing completed with Happel-type boundary conditions which dictate no slip on spheroid and shear...

The dynamics of saturated vapor between two intersecting walls is examined. It shown that, if the angle $\phi$ sufficiently small, becomes unstable, and spontaneous condensation occurs in corner, similar to so-called capillary into a porous medium. As result, an ever-growing liquid meniscus develops near corner. diffuse-interface model lubrication approximation are used demonstrate that grows o...

The responses of Earth's and Mars' thermospheres to the quasi-periodic (27-day) variation of solar flux due to solar rotation were measured contemporaneously, revealing that this response is twice as large for Earth as for Mars. Per typical 20-unit change in 10.7-centimeter radio flux (used as a proxy for extreme ultraviolet flux) reaching each planet, we found temperature changes of 42.0 +/- 8...

Empirical constraints of fundamental properties protoplanetary disks are essential for understanding planet formation and planetary (1,2). Carbon monoxide (CO) gas is often used to constrain disk (3). However, estimates show that the CO abundance in depleted relative expected values (4,5,6,7), models various processes impacting could not explain this depletion on observed 1Myr timescales (8,9,1...

A super–rotating atmosphere with equatorial winds of ∼ 35m s is simulated using a simplified Venus General Circulation Model (GCM). The equatorial super-rotation in the model atmosphere is maintained by barotropic instabilities in the the mid–latitude jets which transport angular momentum towards the equator. The mid–latitude jets are maintained by the mean meridional circulation and the moment...

In this paper a two impinging streams cyclone contacting system suitable for handling of solid-liquid systems has been studied. Certain pertinent parameters such as: solid holdup, mean residence time and Residence Time Distribution (RTD) of solid particles have been investigated. A stochastic model based on Markov chains processes has been applied which describe the behavior of solid partic...

We perform numerical simulations of the Kelvin-Helmholtz instability in the mid-plane of a protoplanetary disc. A two-dimensional corotating slice in the azimuthal–vertical plane of the disc is considered where we include the Coriolis force and the radial advection of the Keplerian rotation flow. Dust grains, treated as individual particles, move under the influence of friction with the gas, wh...
