Abstract (en)
A turbine for generating power in a fluid stream comprises a tubular housing (1) in which a tubular turbine blade carrier body (2) is supported by a bearing assembly (3). One or more turbine blades (4A-D) protrude from an inner surface of the tubular carrier body. The turbine blades (4A-D) have free tips that surround a central opening (5), which provides a passage for equipment and inhibits accumulation of debris and fouling between the turbine blades (4A-D). The turbine is suitable for generating electrical power in wells or pipelines. <IMAGE>
