Cavitation Aggressiveness Estimation in Hydro Turbines Based on Cyclostationary Modeling
(Universidade Tecnológica Federal do Paraná (UTFPR), 2016)
Non-dimensional assessments to estimate decompression failure in polymers for hydrogen systems
(Pergamon-Elsevier Science Ltd, 2020-11)
Polymer materials subjected to gases at high-pressure can have issues during decompression. For instance, a sudden decompression can promote the formation of cavities inside the material. This phenomenon is known as ...
Cavitation in elastomeric solids: II—Onset-of-cavitation surfaces for Neo-Hookean materials
(Pergamon-Elsevier Science Ltd, 2011-08)
In Part I of this work we derived a fairly general theory of cavitation in elastomeric solids based on the sudden growth of pre-existing defects. In this article, the theory is used to determine onset-of-cavitation surfaces ...
Non-invasive detection of vortex street cavitation
(Pontificia Universidad JaverianaUniversidad EAFIT. Departamento de Ingeniería Mecánica, 2017-01-01)
Objective: This paper introduces a methodology for the non-intrusive detection of von Kármán vortex street cavitation. It is based on the cyclostationary analysis of the airborne noise radiated by the collapsing bubbles. ...
Assessment of resistance to xylem cavitation in cordilleran cypress using near-infrared spectroscopy
(Elsevier Science, 2020-04)
Characterizing drought resistance of forest trees is an important aim in the worldwide context of increasing forest decline and dieback. Furthermore, wood demand is increasing all around the world, urging the need for the ...
Cavitation in elastomeric solids: I—A defect-growth theory
(Pergamon-Elsevier Science Ltd, 2011-08)
It is by now well established that loading conditions with sufficiently large triaxialities can induce the sudden appearance of internal cavities within elastomeric (and other soft) solids. The occurrence of such instabilities, ...
Optimizing graphene production in ultrasonic devices
(Elsevier Science, 2020-01)
In this work, we investigate the efficiency of graphene production from graphite by ultrasonic-induced exfoliation under different operational conditions. An ultrasonic bath and an ultrasonic horn tip were used, to show ...
