Abstract

Laboratory experiments were carried out to investigate pressure drop in excess flow safety valve (EFSV) assuming isothermal, incompressible and one-dimensional gas flow. A particular focus was on Reynolds number effects. The analyzed quantities included gas pressure at the EFSV inlet and outlet cross sections, gas flow rate and temperature, as well as open cross-section area of the EFSV. The experiments were performed for various Reynolds numbers, gas inlet pressures and open cross-section area of the EFSV. The results indicated some important findings. In particular, the pressure drop coefficient decreased as the Reynolds number increased. This was particularly exhibited for low Reynolds numbers characterizing laminar flow, while the pressure drop coefficient remained nearly constant in the turbulent flow. The pressure drop coefficient for the approximately equal Reynolds number was larger for smaller EFSV openings. The mathematical expressions linking the Reynolds number, pressure drop coefficient and EFSV opening were provided to enable application of the reported results to pipeline designers.
