Abstract

This paper mainly investigates the convective diffusion of non-Newtonian fluids in fractal main channels. The spatial fractional derivative constitutive equations of non-Newtonian fluids are coupled with the flow equations to derive the governing equations for fluid flow and heat transfer. The shifted Grünwald– Letnikov formula is used to obtain numerical solutions for the model. The effects of fractional derivatives, Reynolds number, and Prandtl number on fluid flow and heat transfer are analyzed.
