Abstract

A numerical simulation study of Venturi overreading characteristics is carried out with Mixture model and Realizable k-e model, and a prediction model of Venturi overreading under low pressure conditions is proposed. Compared with the existing experimental data, it demonstrates that the numerical simulation results have high accuracy, the results indicate that the quality is the main factor affecting the Venturi overreading Meanwhile, the model in this paper is compared with ten classical overreading prediction models such as homogeneous model. It shows that the average prediction deviation of the model in this paper is 3.2%, ranking second, and the maximum prediction deviation is 7.3%. This study can provide reference for the study of Venturi wet gas flowmetering overreading model, and also provide a theoretical basis and options for flowmetering technology.
