Applications of Nanofluid for Heat Transfer Enhancement

4.4. Ferrofluid flow and heat transfer in a semiannulus enclosure in the presence of magnetic source considering thermal radiation

4.4.1. Problem definition

The schematic diagram and the mesh of the semiannulus enclosure used in the present CVFEM program are shown in Fig. 4.18 [8]. The inner wall is under constant heat flux (q″) and outer wall is maintained at constant temperature (T_c), while the two other walls are thermally insulated. In this study, γ equals to 45°. For the expression of the magnetic field strength, it can be considered that the magnetic source represents a magnetic wire placed vertically to the x–y plane at the point $\left(\overline{\text{a}},\overline{b}\right)$.
