Flow loss and structure of circular arc blades with different leading edges
Advances in Mechanical Engineering, 2018 Due to much lower cost of development and production, circular arc blades are often applied to axial flow fans. However, compared with NACA 65 profile, circular arc blades have higher losses, which are caused by the formation of separation bubbles or ...

A Lensed Arc in the Low Redshift Cluster Abell 2124
, 1998 We report the discovery of an arc-like object 27" from the center of the cD galaxy in the redshift $z=0.066$ cluster A2124. Observations with the Keck II telescope reveal that the object is a background galaxy at $z=0.573$, apparently lensed into an arc ...

Effect of electrode geometry on maximum arc pressure in gas tungsten arc welding.
QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 1985 Effects of an electrode geometry on the maximum arc pressure at a base metal were investigated in GTA welding.Results obtained are as follows;(1) The pressure increases with a decrease in a vertex angle of an electrode. But at the vertex angle of 45° the pressure has a peak value and then the pressure decreases with the decrease in the angle less than ...

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control
Advanced Engineering Materials, EarlyView.This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

Double arc instability in the solar corona [PDF]
, 2017 The stability of the magnetic field in the solar corona is important for understanding the causes of solar eruptions. Although various scenarios have been suggested to date, the tether-cutting reconnection scenario proposed by Moore et al.(2001) is one ...

Advanced Engineering Materials, EarlyView.This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...
