Studies on Bio-denitrification of Wastewater Using Immobilized GAC in Draft Tube Spouted Bed Reactor [PDF]

Journal of Environmental Health and Sustainable Development
Introduction: The draft tube-spouted bed bioreactor with GAC particles immobilized with Pseudomonas syringae is being evaluated to study the effect of suspended biomass and biofilm thickness on the rate of denitrification. Though the biofilm thickness is

Heat Transfers in Spouted Beds

Chemical engineering, 1967
内径9.2cmの装置でコークスなど6種頬の粒子を用いて噴流層における壁と層間の伝熱および粒子と流体間の伝熱の研究を行ない, hmについてばEq.(6) を.hpについてはEq.(9) を得た。噴流層におけるhwの値は流動層における値の1/2～1/4であり, hpの値は1/5-1/10であった。Eq.(10) を用いて1側の粒子についてのhpを算出し, 実測値と比較した結果.噴流層では全粒子の数%が噴流部に存在していることが推測される。

Evaluation of Interphase Drag Models for the Determination of Gas Hold-Up of an Air-Water System in a Spouted Bed using CFD [PDF]

, 2011
: The hydrodynamics of a dispersed air-water system within a spouted column with a concentric draft tube and a conical base is simulated using CFD based on a two–fluid Euler–Euler (E-E) modeling framework and k-ε two-equation turbulence closures.
