Biomass reforming processes in hydrothermal media
… of biomass, a supercritical-water reverse-flow vessel (RFV) may be employed to precipitate the salts from the biomass before the biomass is brought into contact with catalysts. However, these vessels are subject to blockage, and flow characterization within the vessels has largely been …

Investigating the Effects of Sparger Design in Column Photobioreactors
… Fluid Dynamics (CFD) is used to predict fluid flow patterns, thermal profiles and additional hydrodynamic and heat transfer parameters in these photobioreactors. The gas bubbles and the water-based media within the photobioreactor are modeled using the Lagrangian-Eulerian approach. A low …

Gas holdup in a gas-liquid-fiber semi-batch bubble column
… and 2.14% is employed to study gas holdup and flow regime in Rayon and Nylon fiber suspensions. This study determines the effect of superficial gas velocity, fiber type, fiber mass fraction, fiber length, and aeration plate open area ratio on gas holdup and flow regime transition in various …

Dense-phase pneumatic transport of cohesionless solids
… lexan which allows for visual observation of the flow pattern. The particles used were a mixture of 95% white and 5% black polyethylene granules (particle diameter approximately 3 mm). The black particles were used to aid the visual observation of the flow pattern. The flow patterns ranged from …
