Impact of Ferromagnetic Nanoparticles Submerged in Chemically Reactive Viscoelastic Fluid Transport Influenced by Double Magnetic Dipole

The present article summarized the effects of double magnetic dipole for chemically reactive viscoelastic fluid in the presence of two different ferromagnetic particles, namely, nickel zinc ferrite ( N i Z n F e 2 O 4 ) and magnetite ferrite ( F e 3 O 4 ). Due to double magnetic dipole, an external magnetic field is applied normal to the flow. Blood is used as base fluid due to its viscoelastic fluid properties. The Cattaneo‐Christov heat flux model is used for heat transport phenomena. The physical model is formulated in the form of partial differential equations which are then converted into ordinary differential equations using the suitable transformations. The system is solved numerically using shooting method along with Runge‐Kutta‐Fehlberg method. The characteristics of different parameters like the strength of homogeneous‐heterogeneous reactions ( k 1 and k 2 ), ferrohydrodynamic interaction ( β 1 ), Schmidt number ( S c ), Deborah number ( α 1 a ), and thermal relaxation time ( α 1 c ) on velocity, temperature, and concentration profiles are analyzed through graphs and in tabular form. It has been observed that as magnetic dipole creates a force which attracts the ferrite particles, hence, it slows down the velocity profile. Concentration field depresses due to the presence of strength of heterogeneous reaction parameter k 2 .It is also noted that by expanding values of thermal relaxation time ( α 1 c ), the temperature profile shows a reverse behavior.
