Abstract

Results of numerical and physical simulations of a junction flow around a three-row cylinder group mounted on the rigid, hydraulically smooth flat surface are presented. Numerical model is based on the vortex method used to integrate 2D Navier–Stokes equations. Experimental researches are carried out in the open hydraulic channel where color inks and contrasting water-soluble coating are applied for visualization of the jet flows and vortex structures generating inside this group. Derived velocity fields demonstrate that the most intense lateral flows form between the first and second as well as between the penultimate and midday cylinders. The currents give rise to developing of large-scale coherent horseshoe vortices at the foot of the cylinders. The size, rotation frequency and angular velocity of the vortices were measured. The estimations show that the vortex generated between the first and second cylinders are more intense than the vortex locating before the group.
