摘要：

A new hydropower plant for converting hydraulic energy of small rivers into work by local restructuring of water flow in spiral form through a conical channel in the form of gravitational vortex is proposed. In water vortex thus formed at different heights of conical channel, runner blades are positioned in steps, twisted at periphery and having special profile. Speed of the runner step increases through the conical channel height in axial flow direction. In this paper are presented the results of numerical simulation of the water flow through the conical channel - in absence of the runner steps as the first approximation.
