ABSTRACT
In this paper, the internal turbulent dissipation rate of nozzle flowmeter under different working conditions is studied, and its distribution characteristics are found. The physical model is used to model, and the motion law is obtained by using the knowledge of fluid mechanics and Navier Stokes equation.In this study, eight kinds of steady flow values were used for the experiment, the experimental results show that the turbulent dissipation rate of the nozzle flowmeter is positively correlated with the flow rate. The results of this paper can be used for more accurate analysis of nozzle flowmeter, and can also be used to provide theoretical basis for the optimization of nozzle flowmeter equipment.
