Accessing the thermodynamics of Walter‐B fluid with magnetic dipole effect past a curved stretching surface

Abstract

AbstractThe effects of magnetic dipole, porosity and heat transfer on the flow of ferromagnetic Walter‐B fluid past a curved stretching sheet is investigated with the gyrotactic microorganisms motion and cubic autocatalysis chemical reactions. The momentum, energy, homogeneous–heterogeneous chemical reactions and gyrotactic microorganisms motion equations, form the problem's governing equations, which are transformed into non‐linear ordinary differential equations via similarity transformations and are solved using an efficient and strong technique namely homotopy analysis method. The effects of the parameters under consideration on dimensionless velocity, temperature, homogeneous–heterogeneous chemical reaction, and motile microorganisms are graphically depicted and discussed in detail. Velocity decreases with the increasing values of curvature parameter while the magnetic dipole effect and Curie temperature parameter increase the heat transfer. The homogeneous chemical reaction and the motile density of microorganisms are enhanced with the rising values of elasticity and ferromagnetic interaction parameters.
