Hertz potentials approach to the dynamical Casimir effect in cylindrical cavities of arbitrary section
(IOP Publishing, 2005-12)
We study the creation of photons in resonant cylindrical cavities with time-dependent length. The physical degrees of freedom of the electromagnetic field are described using Hertz potentials. We describe the general ...
S-band elliptical–cylindrical cavity resonator for material processing
(2022)
The development of an elliptical–cylindrical cavity for microwave thermal processing of materials at high electric field strengths is reported. The design methodology based on numerical modeling is validated by experimental ...
Heat Conduction Equation Solution in the Presence of a Change of State in a Bounded Axisymmetric Cylindrical Domain
(ASME-AMER SOC MECHANICAL ENG, 2011)
The heat conduction problem, in the presence of a change of state, was solved for the case of an indefinitely long cylindrical layer cavity. As boundary conditions, it is imposed that the internal surface of the cavity is ...
Influence of the power level of an ultra-sonic system on dental cavity preparation
(2007-12-31)
The aim of this study was to evaluate the shape of dental cavities made with the CVDentus® system using different ultrasound power levels. One standard cavity was made on the buccal aspect of 15 bovine incisors with a ...

Antenas de microfita anulares cilíndricas embutidas
(Universidade Federal de Minas GeraisUFMG, 2009-10-30)
This work presents an analysis of cavity-backed cylindrical wraparound antennas. The cavity is filled by a dielectric, called substrate, and is built within an infinite cylindrical conductor. The effects of the cavity on ...
Hydrodynamic structure of the boundary layers in a rotating cylindrical cavity with radial inflow
(Amer Inst Physics, 2016)
A flow model is formulated to investigate the hydrodynamic structure of the boundary layers of incompressible fluid in a rotating cylindrical cavity with steady radial inflow. The model considers mass and momentum transfer ...
Effect of surface material properties and operating conditions on the heat flux and temperature distributions in the cavity receiver of a solar-dish-coupled biomass gasification reactor
(Elsevier, 2021-09)
In this paper, a new 5.8 kW solar biomass gasification reactor is modeled by means of Monte-Carlo ray-tracing method and computational fluid dynamics. The reactor is coupled to the cylindrical cavity receiver of a ...
Implementação do método das características na modelagem de problemas de convecção natural em cavidades cilíndricas
