Low-Gravity Experiments: Shear Testing Takes a Nose Dive
A major challenge to making celestial soil mechanics viable is to re-engineer the profession's toolkit to provide geotechnical solutions without the luxury of ex-situ and in-situ testing as we know them...

Fluidization of the Sand Bed and Sediment Movement in the Surf Zone

Large-Eddy Computation of Horizontal Fluidized Bed by a New Multiphase LES

Potential Flow Instability Theory and Bed Forms
An extended, generalised version of two-dimensional linearised potential flow theory of fully unsteady fluid flow-sediment bed interaction is presented. In contrast to previous potential...

Fluidized Bed Denitrification of Secondary Effluent during Wastewater Reclamation in Southern California
A pilot scale fluidized bed denitrification bioreactor was operated for a period of three years as one unit process in a series designed to repurify secondary effluent for subsequent indirect...

Biological Upflow Fluidized Bed Denitrification Reactor Demonstration Project-Stamford, Ct.
Results of a demonstration project using a biological upflow fluidized bed reactor to remove nitrogen from wastewater treatment plant effluent are described. The reactor was operated at...

The Evaluation of Empty Bed Contact Time on the Biodegradation of Pentachlorophenol using an Anaerobic GAC Fluidized Bed
The objective of this research is to evaluate the effects of decreasing the empty-bed contact time (EBCT) on pentachlorophenol and its intermediates utilizing an anaerobic granular activated...

Biodegradation of 2,4-Dinitrotoluene in a Two Stage System
An anaerobic/anoxic fluidized-bed GAC bioreactor in series with an activated sludge reactor was used to treat 2,4-Dinitrotoluene (2,4-DNT). A simulated high strength wastewater solution...

Plunge-Pool Scour by Inclined Jets
A series of experiments were performed in a sand-bed plunge pool with circular jets produced by nozzles at different angles and elevations and conveying different flow discharges. The...

A Design Manual for Coastal Fluidization Systems
This paper summarizes a recently completed design manual on fluidization systems to manage sand in the coastal environment for sand bypassing at inlets and harbor mouths and for creating...

Tackling Trapped Sediments
Crater-sink fluidization has been used to recover sediment from harbors for the past couple of decades. Can this method bypass sediment around dams and return it to eroded beaches, solving...

Recent Developments of the Carbotek Process for Production of Lunar Oxygen
Carbotek and Shimizu Corporation are conducting joint development work on the further development of the Carbotek Process to produce oxygen from lunar ilemnite by hydrogen reduction. The...
