Abstract

Heat and mass transfer in TEXTILEs are usually simulated using models that consider sorption and condensation. But in ELECTROLYTE solutions, ions existed in fluid passing the TEXTILE can cause a phenomenon called ELECTRIC DOUBLE LAYER. Charges on the TEXTILE pores will attract the ions with opposite charge which will affect the fluid flow. To investigate this effect, Poisson-Boltzmann equation is solved besides the other governing equations of the phenomenon. Net electric charge density is computed from this equation and is applied to liquid diffusion coefficient. In this research, the influence of ELECTRIC DOUBLE LAYER is shown and then the factors affecting the strength of this phenomenon have been studied. One side of the TEXTILE is thoroughly in contact with liquid and the other side is in contact with air. To validate the obtained results, temperature variations in the outer side of the TEXTILE are computed and compared with the available experimental works. There is good agreement between the results. According to the results, applying ELECTRIC DOUBLE LAYER effect in equations causes temperature difference of up to 20 percent in the outer surface of TEXTILE. In addition, time for TEXTILE full saturation when the ELECTRIC DOUBLE LAYER is considered increased more than fivefold. The results show that by reducing the viscosity of fluid the effect of ELECTRIC DOUBLE LAYER on the TEXTILE's outer surface temperature is increased. Porosity and zeta potential are other influential factors which, according to calculations, increasing each effect can accelerate the ELECTRIC DOUBLE LAYER.
