Flow regimes in gas-solid fluidized bed with vertical internals

However, such effect is a function of the physical properties of the used solid particles in which the turbulent transition velocity (Uc) decreased in the case of glass beads and increased in the case of aluminum oxide for both of the configuration designs of vertical internals used in the present work. In addition, the 0.0254 m vertical internals type has been shown to be more efficient either in minimizing the turbulent transition velocity (Uc) and superficial gas velocity within the range of slugging flow regime and increasing the range of the superficial gas velocity within the range of bubbling flow regime or in reducing the pressure drop and pressure fluctuations inside the bed.
