摘要：
Ferrofluids are made out of nanoscale ferromagnetic particles and known as colloidal liquids suspended on a bearer liquid, normally water (H2O) or an organic solvent i e., kerosene. A typically composition would be 5% magnetic particles, 10% surfactant and 85% bearer liquid. Ferrofluid is utilized in rotary seals in computer hard drives, loudspeakers, and MRI (magnetic resonance imaging). It is trusted this research work may explore the specialist to think of consider new uses for this attractive material. Therefore, such effectiveness in mind, mathematical modeling for the second order velocity slip nonlinear entropy optimized Darcy-Forchheimer flow of ferrofluid (FF) is developed towards a stretched surface. The energy equation is discussed in the presence of heat source/sink, dissipation and Ohmic heating or Joule heating. Numerical solutions for the desired ordinary system are contracted via built-in shooting method. The flow parameters are discussed graphically. (C) 2020 Published by Elsevier B.V.
