TRANSIENT THERMAL AND VISCOUS IRREVERSIBILITIES THROUGH A POISEUILLE-BENARD CHANNEL IN PRESENCE OF A MAGNETIC FIELD

DOI: 10.1615/ICHMT.2009.CONV.550
ABSTRACT
The influence of an external magnetic field on transient thermal and viscous irreversibilities in Poiseuille-Benard channel for the laminar flow of an incompressible electrically conducting fluid is numerically investigated by solving the mass, momentum and energy conservation equations. Numerical simulation was performed for Reynolds number (Re) equal to 10 and an irreversibility distribution ratio (φ) equal to 0.1. The Stuart number (N) that describes the magnetic field effect, ranges between 0 and 10. Rayleigh and Prandtl numbers are fixed respectively at 104 and 0.71.
