Disclosed embodiments include a bladeless generator carried by drilling string and disposed to employ mud flow through the drill string or return flow along the exterior of the drill string to drive the bladeless generator utilizing the boundary layer effect of fluid flow across a plurality of disks to generate electricity. The bladeless generator can be spaced apart from the primary flow path so as not to significantly disrupt flow therethrough. A portion of the primary flow path is diverted with flow channels or apertures to direct the diverted portion of the flow tangentially across a portion of the edges of the disks. The bladeless generator can be utilized to power electric downhole equipment, such as monitoring equipment or directional drilling steering equipment. |
