Abstract
In the present work, simulations were performed using Computational Fluid Dynamics (CFD) techniques to evaluate the behavior of a fluid when flowing through a Venturi flowmeter. In addition, the efficiency of the pressure recovery after the tube’s throat was evaluated by modifying its parameters of construction and operation. A complete factorial design 2³ was designed to statistically analyze the simulations, being the factors: velocity, convergent angle and divergent angle. Tubes with a convergence angle of 24.15º and divergent angle of 5.95º, flowing with a velocity of 3.0 m.s-1, presented better results in terms of pressure recovery. The worst result was observed when working with angles of 17,85º of convergence, 8,05º of divergence and velocity of 0,1 m.s-1. Thus, velocity and angle of convergence were shown to be interfering with the pressure recovery efficiency response.
