Pretransitional effects near the convective instability in binary mixtures

Pretransitional Effects in the Rayleigh-benard Instability

Solvation effects in near-critical binary mixtures.

A Ginzburg-Landau theory is presented to investigate solvation effects in near-critical polar fluid binary mixtures. Concentration dependence of the dielectric constant gives rise to a shell region around a charged particle within which solvation occurs preferentially. As the critical point is approached, the concentration has a long-range Ornstein-Zernike tail representing strong critical elec...

The Effects of Thermal Noise in a Rayleigh-Benard Cell Near Its First Convective Instability

In recent experiments on the initial stages of pattern formation in a Rayleigh Benard convection cell, Meyer e t al. I1) observed very irregular patterns. In these experiments, the fluid was subjected to a heat current that varied either linearly or periodically in time from below to above the onset of the first instability. If the side wall of the cylindrical cell was made of a material with a...

Convective Heat Transfer of Binary Mixtures under Flow Boiling Conditions

The present study represents part of an effort in considering the replacement of ethylene-glycol/water mixtures with propyleneglycol/water mixtures for engine cooling in automotive application. Experimental results are presented for the heat transfer coeffic ient under flow boiling conditions for water and mixtures of water with ethylene-glycol and propylene-glycol. The range covered includes t...
