dc.description.abstractA numerical study is carried out on mixed convection and entropy generation of Al2O3/water nanofluid due to a rotating cylinder inside a square cavity. The numerical computations are performed taking the non-homogenous model of Buongiorno into consideration. The inner moving rotating circular cylinder is maintained at a constant hot temperature T-h and the other left and right vertical walls of the cavity are maintained at a constant cold temperature T-c. The bottom and top horizontal walls are maintained as adiabatic. The Galerkin weighted residual method is implemented to numerically solve the governing equations. The Rayleigh number (10(4) <= Ra <= 10(7)), angular rotational velocity (0 <=omega <= 600) nanoparticles loading (0 <= phi <= 0.04) and the dimensionless radius of rotating cylinder (0.1 <= R <= 0.4) are the governing parameters of this study. Numerical results for the streamlines, isotherms, isentropic lines, nanoparticle loading, local and average Nusselt number and Bejan number are obtained and presented graphically. A detailed discussion of the results is performed to highlight the physics of the problem.en_US
