TY - JOUR ID - TI - Impacts of Porous Medium on Unsteady Helical Flows of Generalized Oldroyd-B Fluid with Two Infinite Coaxial Circular Cylinders AU - Ghusoon.Gh.Mohammed AU - Alaa Waleed Salih PY - 2021 VL - 62 IS - 5 SP - 1686 EP - 1694 JO - Iraqi Journal of Science المجلة العراقية للعلوم SN - 00672904 23121637 AB - 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(
