【 摘 要 】

Wet gas which is a gas contains liquid, is encountered in various industrial applications such as oil and gas, power generation and mining plants. Measuring wet gas flow rate is required in many of these applications. Venturi flow meters are frequently used for wet gas flow measurement. This paper describes modeling and computer simulation of wet gas flow in the Venturi flow meters. The model used in this paper is based on an annular flow pattern. In this flow pattern, the gas is travelling in the middle of the pipe and the liquid is travelling along the pipe wall. In addition, it is assumed that some liquid droplets are entrained in the gas core. Then Simulink module of Matlab software has been used to simulate this model. This simulation has been used to compare various methods for correcting over-reading of Bernoulli formula when the same is used to measure wet gas flow rate in Venturi flow meter. By comparing the results obtained from simulation of these correction methods, it was found that some of these correction methods such as De Leeuw method are performing better than the others.
