Natural and laser-induced cavitation in corn stems: On the mechanisms of acoustic emissions
(Instituto de Física de Líquidos y Sistemas Biológicos, 2012-05)
Water in plant xylem is often superheated, and therefore in a meta-stable state. Under<br />certain conditions, it may suddenly turn from the liquid to the vapor state. This cavitation<br />process produces acoustic ...
A New Proposal Using a Turbine in the Reactor with a Cavitation System in the Biodiesel Synthesis
(2017-12-01)
The present research investigates the effect of a cavitation system with a turbine in comparison to the vigorous stirring on the process of biodiesel synthesis by the transesterification reaction using oil (triglycerides) ...
Theoretical modeling and experimental validation of hydrodynamic cavitation reactor with a Venturi tube for sugarcane bagasse pretreatment
(2020-09-01)
A hydrodynamic cavitation reactor with a Venturi tube was modeled through a computational fluid dynamics approach in order to evaluate the influence of pressure ratio, diameter and length of the throat zone. A cavitation ...
Bacterial Inactivation In Artificially And Naturally Contaminated Water Using A Cavitating Jet Apparatus
(ELSEVIER SCIENCE BVAMSTERDAM, 2015)
Functional relationships between wood structure and vulnerability to xylem cavitation in races of Eucalyptus globulus differing in wood density
(Oxford University Press, 2018-02)
Wood density can be considered as a measure of the internal wood structure, and it is usually used as a proxy measure of other mechanical and functional traits. Eucalyptus is one of the most important commercial forestry ...
Analytical–numerical modeling of journal bearings with non-Newtonian fluids and cavitation effects
(2021-12-01)
The search for better performance in internal combustion engines and machines which use hydrodynamic journal bearings has motivated recent studies in lubrication field, with the application of computational fluid dynamics. ...
Improvement of the cavitation erosion resistance of UNS S31803 stainless steel by duplex treatment
(ELSEVIER SCIENCE SA, 2010)
A duplex surface treatment consisting of High Temperature Gas Nitriding (HTGN) followed by Low Temperature Plasma Nitriding (LTPN) was carried out in an UNS S31803 duplex stainless steel. The HTGN treatment was intended ...
Mesoscale plasticity anisotropy at the earliest stages of cavitation-erosion damage of a high nitrogen austenitic stainless steel
(ELSEVIER SCIENCE SA, 2009)
A high nitrogen austenitic stainless steel (0.9wt% N) and an ordinary 304 austenitic stainless steel were submitted to cavitation-erosion tests in a vibratory apparatus operating at a frequency of 20 kHz. The high nitrogen ...
Alternative Apparatus to Evaluate Cavitation Damage
(Asce-amer Soc Civil EngineersRestonEUA, 2009)
A Mass-Conserving Algorithm for Dynamical Lubrication Problems With Cavitation
(ASME-AMER SOC MECHANICAL ENG, 2009)
A numerical algorithm for fully dynamical lubrication problems based on the Elrod-Adams formulation of the Reynolds equation with mass-conserving boundary conditions is described. A simple but effective relaxation scheme ...
