Procedure and apparatus for micromotor extracting energy from a fluid using the excitation of the Karman vortex street.

摘要

Procedure and apparatus for micromotor extraction using fluid energy excitation Street Karman vortex.; The procedure involves passing a fluid in a conduit by appropriate within which is located a prism attached via elastic elements to the walls of said conditions. These elements allow the prism oscillate in a plane containing its axis.; Fluid movement around the prism excited resonantly Street Karman vortex and generates periodic forces around the prism leading to an oscillating movement whose frequency and amplitude depends on the design parameters of the micromotor apparatus and fluid dynamic variables .; The oscillatory movement of the prism is used to extract energy from the fluid. The application of the micromotor is the propulsion and power generation for microsystems.
