The Impacts of Suction and Partial Slip on Ferrohydrodynamics Hybrid Ferrofluid (Fe₃O₄/CoFe₂O₄) over an Inclined Stretching Sheet

Nanotechnology plays a pivotal role in introducing innovative strategies for medical treatment, such as hyperthermia cancer through the utilization of ferrite nanoparticles, such as magnetite (Fe₃O₄) and cobalt ferrite (CoFe₃O₄). The stability of nanoparticles ensures their effective delivery and therapeutic activity. This study is dedicated to exploring the behavior of the hybrid ferrofluid, Fe₃O₄/CoFe₂O₄, in a biopolymer solution composed of ethylene glycol and water that flows over an inclined stretching sheet with a magnetic dipole effect. The primary focus of this investigation lies on examining the influence of suction and slip velocity. The formulated governing partial differential equations are initially transformed into simplified ordinary differential equations using appropriate similarity variables. The numerical solutions are then computed by employing the Keller box method. The obtained results demonstrate that the slip parameter diminishes the velocity profile while enhancing the temperature profile. However, the suction effect retards the movement of the nanoparticle and also decays the heat storage in the hybrid ferrofluid. The slip parameter has reduced the shear stress by 49.86% % and the heat transfer rate by 28.56%, respectively. The suction effect significantly enhances both physical quantities. The ferrite nanoparticles with the magnetic dipole, in terms of the ferrohydrodynamics effect, decline the velocity profile but enhance the temperature profile. These findings are essential in integrating the use of ferrite hybrid nanoparticles in cancer treatment.
