Effect of a magnetic field on the couette forced convection of a buongiorno’s nanofluid over an embedded cavity

The paper investigates the effect of a magnetic field on the forced convection of a nanofluid in a channel with an embedded cavity. The nanofluid is described by the Buongiorno’s model, and a fixed temperature boundary condition is prescribed. The governing equations are written in a dimensionless form and solved numerically by employing COMSOL Multiphysics. The obtained velocity, temperature and concentration fields are presented as function of the governing parameters, and the Nusselt number on the upper boundary is evaluated as well. Particular attention is paid to the effect of the inclination angle of the magnetic field, showing that variations up to 40% may affect the Nusselt number.
