摘要：
In this paper, wet gas flow modeling for the straight section of a throat-extended Venturi meter was studied. A static model based on the separated flow theory was presented. Experiments were carried out within static pressure range of 0.26 similar to 0.86 MPa, gas volumetric flowrate range of 80 similar to 120 m(3)/h, water volumetric flowrate range of 0.3 similar to 4.5 m(3)/h and quality range of 0.07 similar to 0.36. It was obtained that the root mean square of the relative errors of the DP over the straight section calculated from the static model was 8.82%.
