Abstract
Unlike single phase flows, the relationship between the phase flow rate and the pressure drop across a differential pressure device (e.g. Venturi) in multiphase flow measurements is not simple and should include the phase volume fractions or the mass flow quality. The research described in this paper studies the bubbly gas-water two phase flows through a universal Venturi tube. The bubbly flow is assumed to be homogenous in which the two phases are moved with the same velocity (i.e. the slip ratio is unity).
EMBED Equation.in conjunction with the homogenous flow model, was combined with the flow density meter enabling the gas volume fraction and hence the mixture flow rate in bubbly gas-water two phase flows to be determined. It was inferred from the experimental results that the homogenous flow model starts to break when the gas volume fraction increases beyond 17.48%.
