SECOND LAW ANALYSIS FOR MIXED CONVECTION IN NON-NEWTONIAN FLUIDS OVER A HORIZONTAL PLATE EMBEDDED IN A POROUS MEDIUM
要約
Second law characteristics of heat transfer and fluid flow due to mixed convection of non-Newtonian fluids over a horizontal plate with prescribed surface heat flux in a porous medium are analyzed. Velocity and temperature fields are obtained numerically using an implicit finite difference method under the similarity assumption, and these results are used to compute the entropy generation rate Ns, irreversibility ratio Φ, and the Bejan number Be for both pseudoplastic and dilatant fluids. The effects of power-law index n, heat flux variation parameter λ, mixed convection parameter γ, axial distance (x), and viscous frictional parameter, G on the velocity and temperature profiles, dimensionless entropy generation rate Ns, irreversibility ratio Φ, and the Bejan number Be are investigated and presented graphically.
