The chemical percolation devolatilization model applied to the devolatilization of coal in high intensity acoustic fields
(Soc Brasileira Quimica, 2002-05-01)
The chemical percolation devolatilization model (CPD) was extended for the prediction of drying and devolatilization of coal particles in high intensity acoustic fields found in Rijke tube reactors. The acoustic oscillations ...
Experimental aspects of partially premixed pulsating combustion
(2005-12-27)
The pulsating combustion process has won interest in current research due to indications that its application in energy generation can offer several advantages, such as: fuel economy, reduced pollutants formation, increased ...
Ultrasound-assisted hydration of wheat grains at different temperatures and power applied: Effect on acoustic field, water absorption and germination
(2020-09-01)
Wheat has been increasingly employed as malt in the food industry. As the malting process demands long processing time, ultrasound can be a clean intensifying alternative. This work studied the ultrasound-assisted hydration ...
The Chemical Percolation Devolatilization Model Applied to the Devolatilization of Coal in High Intensity Acoustic Fields
(Sociedade Brasileira de Química, 2002-06-01)
Neste trabalho, um modelo de percolação química (CPD), desenvolvido para o cálculo da evolução dos produtos de pirólise de partículas de carvão, foi estendido de forma a ser empregado em regimes de degradação térmica sobre ...

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 ...
Modern Rhodolith-Dominated Carbonates at Punta Chivato, Mexico
(Geodiversitas, 2012)
Rhodolith-dominated carbonate environments, characterized by high abundantes of free-living coralline algae, have been described globally from a wide range of Recent and fossil shallow marine settings. In the present-day ...
Qualidade de dados fluviométricos obtidos através de perfilamento acústico
(2013-05-01)
Acoustic Doppler current profilers are currently the main option for flow measurement and hydrodynamic monitoring of streams, replacing traditional methods. The spread of such equipment is mainly due to their operational ...
