The schematic diagram and the mesh of the semiannulus enclosure used in the present CVFEM program are shown in
Fig. 7.16 [7]. The inner wall is maintained at constant temperatures
Th and the other walls are maintained at constant temperature
Tc (
Th >
Tc). The boundary conditions for concentration are similar to those of temperature. 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
. The components of the magnetic field intensity
