Rates of Heat and Mass Transfers for a Non Darcy Porous Medium Subject to Double Dispersion and Saturated by a Nanofluid

Amina Manal Bouaziz

This work aims to quantify the rates of heat and mass transfers occurred between a vertical and nonisothermal plate immersed into a non-Darcy porous medium and saturated with a weak nanofluid. Double dispersion is assumed and natural convection is the exchange mode. The similarity transformations are involved and the governing system of nonlinear partial differential equations is converted into a set of nonlinear ordinary differential equations via similarities. Results are displayed graphically to illustrate the influence of δ and ξ on the velocity, the temperature and concentration of the species profiles. For a weak nanofluid, the rate of mass transfer is affected strongly by the double dispersion while the rate of heat transfer coefficient is less sensitive to it.
