摘要
A gas flow pattern in the regime of jet spouted bed (or dilute spouted bed) has been analyzed in conical spouted beds using materials of different density and particle diameter. The experimental results have been fitted to an empirical equation for calculation of the interstitial velocity at the contactor axis in jet spouted beds. The general equation proposed relates this property to the geometric factors of the contactor (angle, gamma; and inlet diameter, D-o) and to the operating variables (particle size, d(p); particle density, rho(s); particle shape, phi; stagnant bed height, H-o; and air relative velocity referred to that minimum spouting, U-o/U-oms).
