Heat and mass transfer in binary fluids containing alcohols with the Soret effect

Abstract

In this study, heat and mass transfer in binary systems containing methylcyclohexane and n-alkanol (1-pentanol, 1-hexanol, 1-heptanol, 1-octanol, 1-nonanol, and 1-decanol) at 293.15 K to 323.15 K was investigated considering the mutual diffusion coefficient, thermal diffusion coefficient, Soret effect, and the separation ratio. Soret coefficient \({S_T}\)for methylcyclohexane is positive and indicates that this molecule is enriched in the colder regions of the liquids. Obtained results demonstrate that increasing the alkyl chain length reduces its tendency to move to the warmer regions. This behavior means that molecular forces are reinforced with the alcohol chain length. The new method's advantages over previous methods for calculating the thermal behavior of the mixtures are discussed.

“…However, cooled/heated seawater discharged back to the sea could affect marine life and general sea water quality. Thus, most jurisdictions limit the temperature change to 10 K . Since sea water temperature changes during the year, the water flow will need to be adapted depending on the current sea water temperature (see the Supporting Information).…”
