Popis: | In the case of two-phase vapour–liquid flow, especially for low vapour quality ( This paper shows the results of an experimental research carried out with steam-water two-phase flow through two PSVs having the same orifice diameter (10 mm), but different discharge coefficients and inlet geometry. The experimental results are compared with the predictions obtained using a calculation method based on a homogeneous model with non-equilibrium hypotheses and another method proposed in API Recommended Practice 520, developed with equilibrium hypotheses. The results show that the PSV geometry and the discharge conditions are important factors for choosing the more suitable model for the sizing of a little PSV. |
