Horizontal gradient freeze growth of AgGaGeS4 and AgGaGe5Se12

Journal of Crystal Growth, 2006
Abstract AgGaGeS 4 and AgGaGe 5 Se 12 are promising new nonlinear optical crystals for frequency-shifting 1-μm solid state lasers into the mid-infrared (2–12 μm) spectral range. The quaternary compounds were synthesized by vapor transport in sealed ampoules from high purity elemental starting materials, and crystals were grown by the horizontal ...

Horizontal pressure gradient and Soret effects on the onset of thermosolutal porous convection

Heat Transfer, 2021
The intricacies of a constant horizontal pressure gradient on the onset of Soret-driven thermosolutal porous convection have been investigated. The resulting generalized eigenvalue problem is solved numerically using the Galerkin method and also the ...

Unstably stratified Darcy flow with impressed horizontal temperature gradient, viscous dissipation and asymmetric thermal boundary conditions

International Journal of Heat and Mass Transfer, 2010
The free convection flow in a horizontal porous layer with an adiabatic bottom boundary and a top boundary with a stationary and non-uniform temperature distribution is investigated. The top boundary temperature distribution is assumed to have a constant

Pressure gradient in horizontal liquid–liquid flows

International Journal of Multiphase Flow, 1999
Summary: Pressure gradients were measured during the cocurrent flow of a low viscosity oil (1.6 mPa s viscosity and 801 \(kg/m^{3}\) density) and water in two 1-inch nominal bore horizontal test sections made from stainless steel and acrylic resin, respectively.

Trace gas retrieval including horizontal gradients

Advances in Space Research, 2002
Abstract The development of a software package for the retrieval of vertical trace gas profiles from limb sounding measurements led to the analysis of the radiometric effects of inhomogeneous distributions of pressure, temperature and/or trace gases within simulated atmospheric layers as seen by a limb sounding instrument.

The average horizontal gravity gradient

Geophysics, 1962
Abstract A brief theoretical discussion of the average horizontal gravity gradient is presented. Application of the average horizontal gravity gradient in exploration eliminates the disadvantage of all datum planes by unifying the techniques applied in regular gravimeter work and torsion-balance surveys, thereby resulting in better ...
