Resumo (PT): O presente artigo é dedicado ao estudo de diferentes variáveis caracterizadoras da turbulência em escoamentos rápidos. Entre as diferentes variáveis encontram-se os momentos estatísticos, a média, o desvio-padrão, o coeficiente de simetria (“skewness”) e o coeficiente de achatamento (“flatness”), a taxa de dissipação de energia cinética turbulenta, etc. As medições foram realizadas por meio de um sistema de anemometria Laser por efeito Doppler (LDA). O tratamento do sinal Doppler para efeitos da determinação do espectro é também analisado. Finalmente apresentam-se os resultados obtidos que deverão constituir uma base de dados relativa à análise da turbulência em escoamentos rápidos.
Abstract (EN): The present paper is devoted to the study of different characterizing variables of turbulence in supercritical flows. Among the different variables calculated one has the statistical moments: mean, standard deviation, skewness and flatness; the kinetic energy dissipation rate, etc. The measurements were carried with a LDA system. The LDA signal was processed in order to filter outliers and to allow the determination of the turbulent spectrum. Finally the obtained results for the turbulent variables are presented. These will be part of a data base with turbulence data in supercritical flows
