Abstract

The work considers the motion of rolling waves in inclined passages. This type of waves doesn’t depend on the boundary tension and may exist both in turbulent and laminar flow regimes. The set of Dressler’s hydraulic equations was generalized to describe the resistance of rolling waves to 3D disturbances, and their spectra have been developed. It has been established that positive rolling waves are resistant to 3D disturbances, while negative rolling waves are non-resistant.
