Energy Efficiency of the Orthogonal Unit with Controlled Flap
Abstract
The paper discusses the features of flows inside orthogonal turbines that determine their low efficiency. Proposals are formulated that increase the efficiency of turbines. It is noted that multilevel turbines with one or two fixed blades in each tier, as well as turbines with one spiral blade, are the most effective in unlimited flow. The paper suggests the results of calculations and laboratory tests for optimizing turbines and new proposals for the use of automated flaps on the blades.
