Impacts of Porous Medium on Unsteady Helical Flows of Generalized Oldroyd-B Fluid with Two Infinite Coaxial Circular Cylinders


This article deals with the influence of porous media on helical flows ofgeneralized Oldroyd-B between two infinite coaxial circular cylinders.The fractionalderivative is modeled for this problem and studied by using finite Hankel andLaplace transforms .The velocity fields are found by using the fundamentals of theseries form in terms of Mittag-Leffler equation. The research focused onpermeability parameters,fractional parameters(
