Entropy generation analysis of triple diffusive flow past a horizontal plate in porous medium
The combined natural heat and mass transfer, the so-called thermosolutal convective problem, has become an attractive field of research in many diversified areas. In this paper, for the first time, entropy analysis has been carried out for triple diffusive flow. A comprehensive model is developed for the entropy generation due to fluid friction, porous medium, heat, and mass transfer across a finite temperature and concentration difference in the chemical potential of two salts. In this model, a new term showing the entropy generation due to the coupling of concentration gradients of both salts is included. Furthermore, we have introduced a new mass Bejan number for the salts concentrations. The selected salts include sodium chloride and sucrose, which are added in water with different concentrations. The concentrations of both salts are assumed to be higher at the surface. The previously established dimensionless governing equations with Boussinesq approximation and Darcy law were solved numerically. The resulting velocity, temperature, and concentration gradients are employed in the entropy generation model. The impacts of the pertinent parameters and related dimensionless numbers on the dimensionless entropy generation rate, irreversibility ratio and Bejan numbers are examined for both assisting and opposing flows. It has been found that entropy generation rates are higher for assisting flows than opposing flows. At the same time, it is possible to reduce the entropy generation rate with a rise of the Darcy and Lewis numbers while the mass Bejan number increases with Lewis number. (C) 2020 Elsevier Ltd.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 18997-19-8 is helpful to your research. HPLC of Formula: C6H11ClO2.
