Résumé :
|
The experimental study of the air how through a packed bed has been done under working conditions close to those used in the case of drying. The measuring of the local velocities has been done for long beds (L/D > 1), high dimensions pellets (d > 5 mm) and in the domain of intermediate how (Re = 100-400). To correlate the obtained results there has been used as dimensionless velocity the ratio between the local velocity of the air inside the bed and the local velocity of the air in the empty column. The deduced equations have shown that the velocities distribution is influenced by the Re number, the D/d ratio and the L/d ratio.
