The present study examines the linear instability characteristics of double-diffusive mixed convective flow in a vertical channel with viscosity stratification. fluid is modeled as an exponential function temperature and concentration, activation energy parameter determining its sensitivity to variation. Three scenarios are considered: buoyancy force due thermal diffusion only, solute acting sa...

The steady dense granular flow in a vertical channel bounded by flat frictional walls one horizontal direction and with periodic boundary conditions the other directions is studied using discrete element method. shape of scaled velocity profile characterized quantitatively universal exponential function, ratio maximum slip velocities independent average volume fraction $\bar {\phi }$ width $W$ ...

Results of an experimental and theoretical study of the interaction of a first mode internal solitary wave with a localised bottom topography (sill) are presented. Laboratory experiments have been performed in a 10m long and 0.33m wide channel filled with a stratified fluid. The interface between the two layers (fresh and salt water) is diffuse and has a finite thickness. Soliton-type disturban...

Massive multiple-input multiple-output (MIMO) systems, which utilize a large number of antennas at the base station, are expected to enhance network throughput by enabling improved multiuser MIMO techniques. To deploy many antennas in reasonable form factors, base stations are expected to employ antenna arrays in both horizontal and vertical dimensions, which is known as full-dimension (FD) MIM...

This paper presents the design, fabrication and characterization of 4H-SiC trenched-andimplanted vertical JFETs (TI-VJFETs) [1]. The design of TI-VJFETs with active areas of 9.38×10 -2 mm 2 and 2.03mm 2 and different vertical channel openings is presented based on a blocking layer of 9.4μm, doped to n=7x10 15 cm -3 . Highly vertical channel defined by trench etching and angled implantation of A...

Models of the sedimentary architecture submarine channel-levee systems and their formative flow processes are predominantly based on studies from low latitude settings. Here, we integrate high-resolution seismic reflection, bathymetry GLORIA side scan data to document interpret a series ultra-high (72–76°N) that feed lobe complexes off Greenland margin. We demonstrate channel-fills dominated by...

In this paper, the electrical characteristics and sensitivity analysis of staggered type p-channel heterojunction electron-hole bilayer tunnel field effect transistor (HJ-EHBTFET) are thoroughly investigated via simulation study. The minimum lattice mismatch between InAs/GaAs0.1Sb0.9 layers besides low carrier effective mass of materials provides high probability ...

abstract study of turbidity current hydrodynamics plays an important role in increasing the economical life of dams though reduction in sediment accumulation. in the present experimental study, the effect of entrance densimetric froude number of turbidity current in sub and super critical conditions (fr =0.6-3.5) have been tested through effect of channel slope and change related to opening hei...

In this article, the effects of viscous dissipation and inertial force on the velocity and temperature distributions of the mixed convection laminar flow in a vertical channel partly filled with a saturated porous medium have been studied. In this regard, the Brinkman–Forchheimer extended Darcy model was adopted for the fluid flow in the porous region. In addition, three different viscous dissi...
