摘要：A numerical analysis is carried out for unsteady evaporation of a Newtonian fluid Couette flow confined within a cylindrical annulus with relative rotation. The inner wall is humid and adiabatic, whereas the outer one is isothermal and impermeable. The present hydrodynamic and heat-transfer fields are obtained numerically using the finite volumes method. Main attention was paid to the effect of geometrical and thermodynamic parameters on the entropy creation and air evaporation. The results show that the volumetric entropy generation due to thermal conduction and mass diffusion is distinctly developed compared to entropy generated by fluid friction.
