RISTheoretical Analysis and Photothermal Experimental Study of a Segmented Specular Reflection Solar Concentrator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a segmented specular reflection solar concentrator is proposed. Many mirrors are arranged in the same plane, and all the reflected rays fall on the cylindrical focal surface. The glass mirrors are placed in ...
Folding Responses of Origami-Inspired Structures Connected by Groove Compliant Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The compliant mechanism can effectively reduce friction and eliminate the joint gap during the motion. The performances of compliant joints directly determine the overall behavior of mechanisms. In this paper, a new type ...
Efficient Aerodynamic Uncertainty Quantification for a Three-Dimensional Transonic Fan Rotor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Manufactured compressor blades deviate from their intended design, leading to a shift in the mean and scattering of aerodynamic performance. To mitigate performance deterioration without increasing manufacturing costs, an ...
Graphene Oxide–Supported Cobalt Phthalocyanine as Heterogeneous Catalyst to Activate Peroxymonosulfate for Efficient Degradation of Norfloxacin Antibiotics
Publisher: American Society of Civil Engineers
Abstract: Developing highly potent and environmentally friendly catalysts to activate peroxymonosulfate (PMS) to generate reactive species has received considerable and increasing attention in the field of antibiotics elimination. ...
Mitigating Interwell Fracturing Interference: Numerical Investigation of Parent Well Depletion Affecting Infill Well Stimulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Frac hits were not unfamiliar in tight gas development. During the hydraulic fracturing process in infill well, due to closely spaced wells and parent well depletion, operators often encounter fracture interference between ...
Mobility and Kinematic Bifurcation Analysis of Origami Plate Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bifurcation behavior analysis is the key part of mobility in the application of origami-inspired deployable structures because it opens up more allosteric possibilities but leads to control difficulties. A novel tracking ...
Experimental and Numerical Study on the Reduction of Residual Stress in the Fillet Weld by Overlay Welding and Cutting Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fillet weld joint is widely used in engineering structures, but a lot of failures have been generated in the fillet joint affected greatly by weld residual stress, and it is very important to decrease the residual stress. ...

Effect of Helix Angle on Hydrogen Diffusion of Spiral Weld Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a study of hydrogen diffusion for a spiral weld pipe considering the effect of weld residual stress. The results show that the hydrogen mainly gathers at heat-affected zone (HAZ). HAZ is the weakest ...
Estimation of Uplift Capacity of a Single Pile Embedded in Sand Considering Arching Effect
Publisher: American Society of Civil Engineers
Abstract: This note presents an analytical method for predicting the uplift capacity of a single pile embedded in sand, considering the arching effect. Taking into account the passive stress state of dense sand and the active stress ...
