Based on Reynolds Stress Model (RSM), numerical simulation of flow field around Bypass Crossover Sub in the fracturing process of horizontal wells is carried out by Computational Fluid Dynamics (CFD) analysis. Distribution rules of axial velocity, tangential velocity and radial velocity of fluid field in calculation region are achieved. Results show that strong vortexes and reverse flow exist at the slots on Bypass Crossover Sub, which brings the impact of the fluid on the wall at certain angle. Impacting velocity and angle at different positions of the wall are studied in detail. A Laser Doppler Anemometer (LDA) is applied to examine the flow field velocity distribution. Experimental results agree well with the numerical simulation results, which prove the validity of turbulence model and computational method. Numerical simulation is carried out at different Length-Breadth ratio of slots on the Bypass Crossover Sub. Effect of the Length-Breadth ratio on the scale of vortexes, speed distributions and flow field near the wall area is discussed. All of these will provide some reference on structural optimization and the analysis of erosion.
