AB - This paper examines the fascinating phenomenon of fractal  convection-diffusion in a porous nanofiber membrane. A multi-scale  artificial intelligence model has been developed, in which the temporal  Caputo fractional derivative, the spatial Riesz fractional derivative, and  the traditional derivative for the convection process have been employed.  The convection-diffusion process exerts a significant influence on the  permeability of the nanofiber membrane. This paper examines the influence of  the convection process on the permeability of the membrane. The findings  indicate that when the fluid velocity is minimal, the diffusion process  assumes control. However, when a certain threshold is reached, the  convection process assumes dominance, accelerating the permeability process.  The direction of the fractal convection-diffusion process is predominantly  influenced by the direction of the fluid-flow.
