Forchheimer Flow

Three-dimensional Darcy–Forchheimer flow of nanoliquid due to a rotating disk subject to multiple slip conditions is examined in this study. Thermophoresis and Brownian motion along with heat and mass transfer are incorporated. Slip conditions of velocity, concentration, and temperature are executed. Similarity results are established via MATLAB routine bvp4c. Graphs of velocities, temperature, and concentration are sketched to discuss the impacts of several influential parameters. Numerical values of skin frictions and local Sherwood and Nusselt numbers are calculated and inspected. Our findings display that concentration and temperature are enhanced for larger thermophoresis parameter.

Purpose This study aims to deal with the laminar flow owing to rough rotating disk in the existence of vertical magnetic field and partial slip effects. The aim is to resolve heat transfer problem in the existence of non-linear radiative flux and thermal slip effects. The study also analyzes the mass transfer process when the flow field contains chemically reacting species. Design/methodology/approach Modified von-Kármán transformations are applied to change the conservation equations into similar forms. The transformed equations are treated by a convenient shooting method and by contemporary built in routine bvp4c of MATLAB. Findings The numerical solutions are used to address the role of main ingredients of the problem, namely, wall roughness, radiation and chemical reaction on the flow fields. Research limitations/implications Temperature profiles are considerably affected by a parameter measuring wall to ambient temperature ratio. Furthermore, behavior of concentration field is highly influenced by the reaction rate of the diffusing species. Originality/value The concept of non-linear radiation in chemically reactive flow over a rotating disk is just introduced here.

Forchheimer Flow

Purpose The purpose of this study is to examine the Darcy–Forchheimer flow of viscous nanoliquid because of a rotating disk. Thermophoretic diffusion and random motion aspects are retained. Heat and mass transfer features are analyzed through convective conditions. Design/methodology/approach The governing systems are solved numerically by the shooting technique. Findings Higher porosity parameter and Forchheimer number Fr depict similar trend for both velocity profiles f' and g. Both temperature and concentration profiles show increasing behavior for higher Forchheimer number Fr. An increase in Prandtl number Pr corresponds to lower temperature profile, while opposite trend is noticed for thermal Biot number. Larger concentration Biot number exhibits increasing behavior for both concentration and its associated layer thickness. Originality/value To the best of the author’s knowledge, no such consideration has been given in the literature yet.
