Previous issue date: 2010-11-24 / This work proposes a model to investigate the use of a cylindrical antenna used in
the thermal method of recovering through electromagnetic radiation of high-viscosity oil.
The antenna has a simple geometry, adapted dipole type, and it can be modelled by using
Maxwell s equation. The wavelet transforms are used as basis functions and applied
in conjunction with the method of moments to obtain the current distribution in the antenna.
The electric field, power and temperature distribution are carefully calculated for
the analysis of the antenna as electromagnetic heating. The energy performance is analyzed
based on thermo-fluid dynamic simulations at field scale, and through the adaptation
in the Steam Thermal and Advanced Processes Reservoir Simulator (STARS) by Computer
Modelling Group (CMG). The model proposed and the numerical results obtained
are stable and presented good agreement with the results reported in the specialized literature / Neste trabalho ? proposto um modelo para investigar o uso de uma antena cil?ndrica
utilizada no m?todo t?rmico de recupera??o por irradia??o eletromagn?tica de petr?leo
de alta viscosidade. A antena apresenta uma geometria simples, do tipo dipolo adaptada,
e pode ser modelada usando-se as equa??es de Maxwell. As transformadas de wavelets
s?o usadas como fun??es de base e aplicadas em conjunto com o m?todo dos momentos
na obten??o da distribui??o de corrente na antena. O campo el?trico, a distribui??o
de energia e a temperatura s?o cuidadosamente calculadas para analise da antena como
aquecedor eletromagn?tico. O desempenho energ?tico ? analisado a partir de simula??es
termo-fluidodin?micas em escala de campo, atrav?s da adapta??o no Steam Thermal and
Advanced Processes Reservoir Simulator (STARS) da empresa de software Computer
Modelling Group (CMG). Os resultados obtidos para po?os constitu?dos por ?leos viscosos
s?o est?veis e apresentam boa concord?ncia com resultados da literatura
