RISInnovative Remedial Technologies for Subsurface Contamination
Publisher: American Society of Civil Engineers
A Benchmark Artifact to Evaluate the Manufacturing of Microfeatures by Digital Light Processing Stereolithography
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Suitable benchmark artifacts are needed for assessing the technological capabilities and limitations of a specific process or for comparing the performances of different processes. Only a few benchmark artifacts have been ...
Constructive and Destructive Interplay Between Piezoelectricity and Flexoelectricity in Flexural Sensors and Actuators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flexoelectricity is an electromechanical effect coupling polarization to strain gradients. It fundamentally differs from piezoelectricity because of its sizedependence and symmetry. Flexoelectricity is generally perceived ...
New Model of a Basin-Type Solar Still
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermal and productivity measurements and flow visualization experiences were performed on a real scale module of a basin type solar still, whose geometry and thermal conditions could be changed ...
Pulsatile Poiseuille Flow of a Viscoplastic Fluid in the Gap Between Coaxial Cylinders
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Several materials that are of interest in engineering present a yield stress and behave as viscoplastic fluids. This paper investigates numerically the motion of a Bingham fluid between two ...
Unsteady Flow of Fluids With Arbitrarily Time-Dependent Rheological Behavior
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an analytical solution of the momentum equation for the unsteady motion of fluids in circular pipes, in which the kinematic viscosity is allowed to change arbitrarily in time. Velocity and flow rate are ...
Comparative Study of Gaussian Dispersion Formulas within the Polyphemus Platform: Evaluation with Prairie Grass and Kincaid Experiments
Publisher: American Meteorological Society
Abstract: This paper details a number of existing formulations used in Gaussian models in a clear and usable way, and provides a comparison within a single framework?the Gaussian plume and puff models of the air quality modeling ...
Flow and Erosive Stresses at the Base of a Headcut
Publisher: American Society of Civil Engineers
Abstract: This paper revises current understanding of the flow at the base of a headcut and suggests a new model which employs the concept of a vortex flow. A distinctive feature of the vortex flow is the presence of the upstream-directed ...
Innovative Waste Containment Barriers for Subsurface Pollution Control
Publisher: American Society of Civil Engineers
Abstract: Bentonite modified by cationic surfactants has been the focus of attention for engineering applications such as in horizontal cut-offs, grout mixes, cut-off slurries, soil motars, and landfill liners because of its high ...
Solidification/Stabilization of Phenolic Waste Using Organic-Clay Complex
Publisher: American Society of Civil Engineers
Abstract: The solidification/stabilization (S/S) process is applicable to soil contaminated by metals and other inorganics. However, this process is not currently viewed by the U.S. Environmental Protection Agency (EPA) as applicable ...
