Method and system of providing fluid flow for a rotor

A fluid routing device for providing conducted fluid to a blade, comprising:

• a continuous channel with an inlet and an outlet, said continuous channel conducts fluid passing via said inlet when mounted on a blade of a rotor having a plurality of blades;
• a blade attachment element for attaching said fluid routing device to said blade so that said inlet being placed in a lateral edge of said blade, facing the opposite direction of rotation of said plurality of blades;
• and a flow directing element connected to said outlet and directs said conducted fluid to adjust fluid flow in or on said blade when mounted on said blade;
• wherein said rotor is a vertical axis wind turbine (VAWT) and said fluid routing device being mechanically connected to at least one of a top lateral edge and a low lateral edge of said blade so that a phase shift formed by said fluid passing via said inlet increases a stagnation pressure as compared to that prevailing at the tip of said lateral edge.

A method of flowing conducted fluid in a system having a rotor with a plurality of blades, comprising:

• attaching a fluid routing device having a continuous fluid channel with an inlet to a blade of a rotor having a plurality of blades so that said inlet being placed in a lateral edge of said blade and facing the opposite direction of rotation of said plurality of blades:
• altering the static pressure of fluid conducted via said inlet in said continuous fluid channel;
• and
• directing said pressure altered fluid for adjusting fluid flow in or on said blade.

A rotor, comprising:

• a plurality of blades;
• and
• at least one fluid routing device, each mechanically connected to one of said plurality of blades and comprises:
• a continuous channel with an inlet, placed in a lateral edge of a respective said blade and facing the opposite direction of rotation of said plurality of blades and an outlet, said continuous channel routes fluid passing via said inlet so as to form a sub-ambient pressure at said lateral edge which attracts fluids from at least one of a lumen in said blade and the surface of said blade;
• wherein said rotor is a vertical axis wind turbine (VAWT) and said continuous channel being located in at least one of a top lateral edge and a low lateral edge of said blade so that a phase shift formed by said fluid passing via said inlet increases a stagnation pressure as compared to that prevailing at the tip of said lateral edge.
