چکیده
In this work time dependent heat transfer flow through a kerosene based ferrofluid is considered. The flow is in a cylindrical geometry with the height and diameter of 10 mm. Computational fluid dynamics was used to simulate the system. In CFD simulations mixture model was applied to describe the behavior of the magnetic particles. A uniform magnetic field with different strengths and directions were used over the system. Numerical results illustrate that compare to the field free case, in the presence of magnetic field the transport processes will enhance. It was obtained when magnetic field’s direction is perpendicular to the temperature gradient, heat transfer significantly will increase.
