...Basanta Kumar Rana; Jnana Ranjan Senapati An objective function combining the first and second laws of thermodynamics has been employed to delineate the thermodynamic performance on mixed convection around a vertical hollow, rotating cylinder within the laminar range with the variation of Rayleigh...

... the wall surfaces of rotating vertical hollow cylinders (Re D  ≠ 0) is compared with the case of the stationary cylinder (Re D  = 0). The rate of heat transfer is higher in the case of a rotating cylinder in comparison to a nonrotating one. Table 2 shows the percentage of increase in the heat...
