| Popis: | This work is devoted to the three–dimensional numerical simulations of the heat and fluid flow past and through a porous spherical particle over a wide range of Reynolds numbers (20 100) a local maximum in the drag force coefficient was observed for a porosity of about 0.76. On the basis of the results of simulations, expressions are derived and examined for the drag coefficient and the surface–averaged Nusselt number. |
