(2016-07-01)
Objective: To evaluate stainless steel archwire static friction in active and passive self-ligating lingual and conventional brackets with secondorder angulations. Methods: Two conventional lingual brackets for canines ...
Friction behavior of lubricated zinc phosphate coatings
(ELSEVIER SCIENCE SA, 2009)
The aim of the present work is to elucidate the influence of lubricants on the friction behavior of zinc phosphated coatings and provide an explanation for the results in terms of physical-chemical interactions between ...
Friction factors, convective heat transfer coefficients and the Colburn analogy for industrial sugarcane juices
(Elsevier B.V. Sa, 2012-01-15)
Sugarcane (Saccharum sp.) is a relatively low-cost agricultural resource, produced mainly in tropical and subtropical regions of the planet. One of the most important applications of sugarcane juice is in the production ...
Laminar flow of soursop juice through concentric annuli: Friction factors and rheology
(Elsevier B.V., 2007-02-01)
Laminar axial flow of a pseudoplastic fluid food (soursop, juice) in annular ducts has been experimentally investigated. In the first part of the manuscript, the rheological behavior of soursop juice, being essential for ...
Influence of friction and asymmetric freeplay on the limit cycle oscillation in aeroelastic system: An extended Henon's technique to temporal integration
(Elsevier B.V., 2020-07-01)
Nonlinear effects such as friction and freeplay on the control surfaces can affect aeroelastic dynamics during flight. In particular, these nonlinearities can induce limit cycle oscillations (LCO), changing the system ...
Development of friction-induced triboluminescent sensor for load monitoring
(2018-03-01)
Real-time load monitoring of critical civil and mechanical structures especially dynamic structures such as wind turbine blades is imperative for longer service life. This article proposed a novel sensor system based on ...
