RISEvaluation on Applicability of Reynolds Equation for Squared Transverse Roughness Compared to CFD
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A discrete probability distribution function is used to represent the squared transverse roughness effect in a modified Reynolds equation, and the Reynolds equation is used to calculate the ...
Degradation Kinetic and Remediation Effectiveness of 1,4-Dioxane-Contaminated Groundwater by a Sono-Activated Persulfate Process
Publisher: American Society of Civil Engineers
Abstract: The well-known biorefractory organic material 1,4-Dioxane (1,4-D) is difficult to degrade in groundwater by classical treatment processes. The sono-activated persulfate process was applied to remediate 1,4-D-contaminated ...
Study of Drag Forces on a Designed Surface in Bubbly Water Lubrication Using Electrolysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To study the drag reduction effect of a bubbly fluid, a pin-disk experiment is performed on the Universal Micro Tribotester system. Bubbles are generated by water electrolysis in holes that ...
A Linear Least Squares Algorithm for Double Wiebe Functions Applied to Spark Assisted Compression Ignition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An algorithm for determining the four tuning parameters in a doubleWiebe description of the combustion process in sparkassisted compression ignition engines is presented where the novelty is that the tuning problem is posed ...
Vibration of Prestressed Cable RC Truss Floor System due to Human Activity
Publisher: American Society of Civil Engineers
Abstract: Vibration has become a serious serviceability problem due to the large openings of girder, lightweight floor systems, and high-strength materials used in practice. The results from both heel-drop and jumping floor vibration ...

Unconditionally Stable Explicit Displacement Method for Analyzing Nonlinear Structural Dynamics Problems
Publisher: American Society of Civil Engineers
Abstract: This paper introduces a novel approach based on dimensional analysis for designing explicit displacement algorithms for use in analyzing nonlinear structural dynamics problems. Using this approach, a one-parameter family ...
Turning Parameters Optimization for Diffraction Effect Suppression of Diamond-Turned Surface Combining Surface Micro-Topography Model and Scattering Theory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The diamond-turning process is a mean optical surface generation technique with high figure accuracy and surface finish. The diamond-turned surface has a significant diffraction effect introduced by the tool marks remaining ...
Design of an Underactuated Finger Based on a Novel Nine-Bar Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Elastic elements are commonly adopted to realize underactuation in the design of human-friendly prosthetic hands. The stiffness of these elastic elements, which is a key factor affecting the grasp performance of the ...
