Abstract
Ferrofluids are useful in numerous industries and sciences, like mechanical and electrical engineering. Recent improvements in nanoelectromechanical systems (NEMS), microfluid, nanofluid, and Ferrofluid indicate the importance of this new scientific field. Various and complex factors reduce the heat transfer process. The low heat transfer coefficient has become a significant concern in many areas of heat transfer, such as small systems. In this chapter, the characteristics of Ferrofluid over a shrinking sheet with an effective thermal conductivity model are studied using the homotopy perturbation method (HPM) and Akbari-Ganji's method (AGM). Also, the Finite Element Method (FEM) has been applied to numerical answers. The governing equations were formulated using the Tiwari-Das model. The influence of related micro-rotation and dimensionless velocity parameters have been taken for suction and injection of mass transfer parameters. Results indicate that the magnetic and boundary parameters, in contrast to the micro-rotation parameter, have the same effect on velocity.
