Abstract The research is devoted to studying of large-scale precessing double vortex arising in two-phase flow in flowing hydrodynamic tangential vortex reactor. The effect of stabilizing and merging of double helix into a single quasistationary columnar vortex by injecting the gas phase into the flow was discovered. The flow structure changing was recorded by means of a high-speed visualization technique. Quantitative measurements characterizing the flow structure were obtained by using laser Doppler anemometry technique.
