A Reduced Model for Salt-Finger Convection in the Small Diffusivity Ratio Limit
Fluids, 2017 A simple model of nonlinear salt-finger convection in two dimensions is derived and studied. The model is valid in the limit of a small solute to heat diffusivity ratio and a large density ratio, which is relevant to both oceanographic and astrophysical ...

Multidimensional quasiballistic thermal transport in transient grating spectroscopy [PDF]
, 2015 Transient grating spectroscopy has emerged as a useful technique to study thermal phonon transport because of its ability to perform thermal measurements over length scales comparable to phonon mean free paths (MFPs).

Measurements of thermal properties of icy Mars regolith analogs [PDF]
, 2012 In a series of laboratory experiments, we measure thermal diffusivity, thermal conductivity, and heat capacity of icy regolith created by vapor deposition of water below its triple point and in a low pressure atmosphere.

THERMOPHYSICAL AND RHEOLOGIC PROPERTIES OF BIOOIL SAMPLES [PDF]
Journal of Central European Agriculture, 2013 This article deals with thermal properties of selected biooils Plahyd S biooil No1 and Plahyd N biooil No2 and rheologic properties of rapeseed oil. Plahyd S is a synthetic, rapidly biodegradable fluid which is based on sustainable raw materials.

Morphological instability of a nonequilibrium icecolloid interface [PDF]
, 2009 We assess the morphological stability of a nonequilibrium icecolloidal suspension interface, and apply the theory to bentonite clay. An experimentally convenient scaling is employed which takes advantage of the vanishing segregation coefficient at low ...

A Fast Semi-implicit Method for Anisotropic Diffusion
, 2011 Simple finite differencing of the anisotropic diffusion equation, where diffusion is only along a given direction, does not ensure that the numerically calculated heat fluxes are in the correct direction.

Compressibility in turbulent MHD and passive scalar transport: mean-field theory
, 2018 We develop a mean-field theory of compressibility effects in turbulent magnetohydrodynamics and passive scalar transport using the quasi-linear approximation and the spectral $\tau$-approach. We find that compressibility decreases the $\alpha$ effect and

International Communications in Heat and Mass Transfer[Abstract] In this study, we numerically investigate the effects of the nonlinearity in the equation of state on the structure of fingers and the transport mechanisms of salt and heat in double-diffusive finger convection, utilizing the finite volume approach with high-accuracy schemes to solve the two-dimensional Navier–Stokes equations. Our system is
