RISExit Flow Field and Performance of Axial Flow Fans
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flow fields near the exit and the global performance parameters of the various types of axial flow fans are studied with Particle Image Velocimetry and a standard AMCA 210 flow bench. The ...
Finite Element Analysis of the Unsteady Thrust Characteristics of Pulse Detonation Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A general, dynamical approach developed a high-fidelity, finite element model of a pulse detonation engine (PDE). The approach deconvolved the structural response due to cyclic acceleration that would be measured by a load ...
Adsorption Characteristics of Oxide Coated Buoyant Media (ρs<1.0) for Storm Water Treatment. I: Batch Equilibria and Kinetics
Publisher: American Society of Civil Engineers
Abstract: Urban rainfall-runoff mobilizes and transports significant loads of metal species. Promulgation of National Pollutant Discharge Elimination System Phase II regulations has spurred development of Unit Operations and Processes ...
Adsorption Characteristics of Oxide Coated Buoyant Media (ρs<1.0) for Storm Water Treatment. II: Equilibria and Kinetic Models
Publisher: American Society of Civil Engineers
Abstract: Divalent metal species adsorption onto a manganese oxide coated polymeric medium (MOPM) was evaluated through batch adsorption experiments using a flow-through batch reactor. In this paper, Part II, the batch equilibrium ...
Comparison of Sorptive Filter Media for Treatment of Metals in Runoff
Publisher: American Society of Civil Engineers
Abstract: Rainfall runoff and snowmelt impacted by anthropogenic activities can transport significant loads of metals. Ecological concerns and recent regulatory guidance have spurred development of unit operations such as ex situ ...
Adsorption Kinetics for Urban Rainfall-Runoff Metals by Composite Oxide-Coated Polymeric Media
Publisher: American Society of Civil Engineers
Abstract: A manganese oxide-coated polymeric media (MOPM) utilized in sorptive filtration systems as a rainfall-runoff or snowmelt unit operation and process media was characterized using scanning electronic microscopy and adsorption ...
Effects of a Shielding Skirt for Prevention of Sea Lice on the Flow Past Stocked Salmon Fish Cages
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of a shielding skirt, a tarpaulin mounted from the surface down to 5 m depth around a net cage, on the flow pattern at a commercially stocked salmon cage was investigated. Dye was used as a tracer for water ...
New Ductile Hybrid FRP Reinforcing Bar for Concrete Structures
Publisher: American Society of Civil Engineers
Abstract: A new ductile hybrid fiber reinforced polymer (FRP) bar has been developed at Drexel University. This new bar is unique in that it has equivalent bilinear stress-strain characteristics, with a Young's modulus approaching ...
Treatment of Arsenic-Contaminated Soils. II: Treatability Study and Remediation
Publisher: American Society of Civil Engineers
Abstract: Treatment of sandy soils contaminated with arsenic was investigated at a bench scale and carried through to remediation in the field. The initial treatability study looked at many combinations of cement binders and reagents. ...
Treatment of Arsenic-Contaminated Soils. I: Soil Characterization
Publisher: American Society of Civil Engineers
Abstract: Industrial sites frequently have arsenic-contaminated soils as a result of repeated applications of arsenic herbicides. Four such sites were investigated to determine the suitability of cement-based solidification/stabilization ...
