Investigation Of Hydrodynamic Scaling Relationships In Shallow Spouted Beds, Irma Deytia Lima Rojas

Doctoral Dissertations

Important global hydrodynamic relationships for shallow spouted beds of high-density particles were characterized in terms of three features: minimum spouting velocity, overall bed pressure drop at minimum spouting velocity; and fountain height. Spouted bed literature is sparse for shallow beds (static particle depth to bed diameter ≤ 1) and beds with heavy particles (density > 3000 kg/m³). Correlations for such beds were developed here by varying column diameter, static bed height, particle diameter, particle density, gas density and gas flow in an ambient temperature and pressure bed.

The degree of correlation between each of the observed hydrodynamic features and …
