Normalized lift: an energy interpretation of the lift coefficient simplifies comparisons of the lifting ability of rotating and flapping surfaces. [PDF]
PLoS ONE, 2012 For a century, researchers have used the standard lift coefficient C(L) to evaluate the lift, L, generated by fixed wings over an area S against dynamic pressure, ½ρv(2), where v is the effective velocity of the wing.

Viscous Frictional Moment between Eccentric Rotating Cylinders when Outer Cylinder Rotates
Bulletin of JSME, 1969 Although many studies on journal bearings have been reported as regards eccentric rotating cylinders, there is no frictional moment (torque) measurement which has been done for various eccentricity ratios and radius ratios in condition that there is sufficient fluid to fill the clearance in journal bearing.

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys
Advanced Engineering Materials, EarlyView.This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Unstable outer cylinder whirl of concentric double rotating cylinder system
Mechanical Engineering Journal, 2023 This research investigates unstable outer cylinder whirl in a double rotating cylinder system, with both co- and counter-rotation, in which the axis of the outer cylinder is supported elastically in the radial direction and the axis of the inner cylinder

Advanced Engineering Materials, EarlyView.Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A
Advanced Engineering Materials, EarlyView.The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.
