According to the principle of Bernoulli Effect in fluid mechanics, a dust measurement pipeline with Bernoulli Effect is designed. According to the previous research of the projec, this paper simulates by CFD software, obtains the particle motion velocity and electrostatic induction under different pipe diameter ratio, and finds out the maximum electrostatic induction under the better tube diameter ratio. The annular electrostatic sensor is used to find a better diameter ratio for Bernoulli Effect tube. The improved device model with different pipe diameter ratio was established in Gambit2.4, and 2D stereo model was used for experimental simulation. The velocity cloud map of particle motion is obtained by using FLUENT6.3 to solve the problem, and the corresponding velocity value is obtained according to the cloud image. The electrostatic induction calculation by MATLAB shows that when the diameter ratio d / D is 0.4 and the velocity is 9.76m/s, the electrostatic induced charge of dust particles is the largest at this time. It has certain guiding significance for the design of dust measurement pipeline.
