Rheological aspects of variable diffusive phenomena in the non-linear stratified second grade nanomaterial under Darcy-Forchheimer theory

In real life applications, variations in diffusivity properties are incorporated in order to estimate accurately the transfer rate of heat/mass. This phenomenon has significant impact on liquid diffusion, electronics, moisture migration process, building insulation, vapors diffusion. Thus, present a...
