Description

In this work the pressure loss of the annular air-liquid flow in vertical tubes has been determined. Correlations are presented for the frictional pressure drop. The dimensional analysis and the following fluid systems were used for this determination: air-water, air-alcohol solutions and air-water and surfactants

Abstract (Portuguese)

Determina-se a perda de carga no escoamento anular liquido-ar em tubos verticais. Apresenta-se as correlacoes para perda de carga por atrito. A analise dimensional e os seguintes foram usados para esta determinacao: agua-ar, ar solucoes de alcool e agua-ar com tensoativos
