Abstract
The dependence of the pressure drop on a gas-liquid mixture due the area contraction ratio is investigated for thin concentric orifice plate. The approach uses two-phase multipliers extracted from air-water experimental data with distinct pipe diameter, orifice's area contraction ratio operating in horizontal and vertical lines. The experimental data disclose for a fixed quality an increase on the two-phase multiplier as the orifice’s contraction ratio increases. It is proposed an improvement on a two-phase multiplier model adding the influence of the orifice’s area contraction ratio as a correction term into the slip ratio.
