RISEffect of Gas Diffusion Layer Surface Wettability Gradient on Water Behavior in a Serpentine Gas Flow Channel of Proton Exchange Membrane Fuel Cell
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Water removal and behavior, in proton exchange membrane fuel cell (PEMFC) gas flow channel has been investigated in this work. Single serpentine gas flow channel has been simulated. Hydrodynamics of water drops in a ...
Atmospheric Corrosivity Map for Management of Steel Infrastructure in India Using ISO Dose–Response Function and Gridded Data
Publisher: ASCE
Abstract: The first-year corrosion rate (K) values of metals measured using standard protocols are indicative of the relative vulnerability of metal infrastructure to atmospheric corrosion at a given location. The Dose–Response ...
Severity of Rain-Induced Wetting–Drying Conditions and the Associated Risk of Concrete Carbonation in the Tropics
Publisher: ASCE
Abstract: Assessing the probability of failure of typically adopted cover depths to resist the onset of carbonation-induced corrosion under the influence of seasonal rains is important for the durability design of reinforced concrete ...
Development of a Scaled-Down Test Rig for Wheel–Rail Contact Thermal Experiments Using Optical Sensors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rail–wheel contact measurement is crucial for several reasons. First and foremost, it directly affects the safety of passengers, crew, and the general public. Accurate measurements help identify irregularities in wheel–rail ...
ADDOPT: An Additive Manufacturing Optimal Control Framework Demonstrated in Minimizing Layer-Level Thermal Variance in Electron Beam Powder Bed Fusion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The large temporal and spatial variations in temperature that can occur in layer-wise metal additive manufacturing (AM) lead to thermal excursions, resulting in property variations and defects. These variations cannot ...
Influence of Initial Water Content and Specimen Thickness on the SWCC of Fine-Grained Soils
Publisher: American Society of Civil Engineers
Abstract: Earlier researchers have demonstrated that the compaction effort and water content, type of soil and mineralogy, void ratio, fabric, and stress history influence the soil-water characteristics curve (SWCC) of fine-grained ...
Multi-Lattice Topology Optimization Via Generative Lattice Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Additive manufacturing enables the fabrication of multi-lattice structures, an advanced design approach featuring heterogeneous lattices at the mesoscale which are arranged to achieve a diverse and purposeful distribution ...
Limitations of Surface Liquefaction Manifestation Severity Index Models Used in Conjunction with Simplified Stress-Based Triggering Models
Publisher: ASCE
Abstract: The severity of surface manifestation of liquefaction is commonly used as a proxy for liquefaction damage potential. As a result, manifestation severity index (MSI) models are more commonly being used in conjunction with ...
True Liquefaction Triggering Curve
Publisher: American Society of Civil Engineers
Abstract: Current simplified models for predicting liquefaction triggering and manifestation do not account for the mechanisms of liquefaction triggering and surface manifestation in a consistent and sufficient manner. Specifically, ...
Formation of Crystalline Metal Nanoparticles by Marine Isolates and Their Microbial Consortium
Publisher: American Society of Civil Engineers
Abstract: The present study reports that microbes from marine sediments can reduce noble metal ions (Au, Ag, and Pt) to their nanoparticles (NPs). The microbes were initially screened for the synthesis of gold (Au) NPs through ...
