FLUID MACHINE HAVING DEVICE FOR CONVERTING FLOW ENERGY OF FLUID INTO SWIRL VORTEX FLOW ENERGY, AND ROTATABLE VESSEL HAVING BLADE TO ENHANCE SWIRL FLOW ON INNER FACE OF ROTATABLE CYLINDRICAL SHAPE

摘要

PROBLEM TO BE SOLVED: To provide a fluid machine using a fluid flowing in a comparatively parallel portion (tap water flowing in water pipe), and capable of converting flow energy of unused fluid into swirl vortex energy without needing positional energy and applying a pressure load to a supply side, and further converting the rotational energy into another energy such as electric energy.SOLUTION: A fluid machine is composed of an axial flow impeller rotatably disposed on a pipe wall for rectifying flow of a fluid, a logarithmic spiral blade fixed to the pipe wall to obtain swirl flow, and a twisted blade for enhancing swirling force, which are successively disposed in a pipe conduit in which the fluid flows, from an upstream side, and a generator is constituted by disposing and fixing a twisted impeller and a centrifugal diagonal flow impeller with a logarithmic spiral blade on the pipe wall of the pipe conduit which is rotatably supported.
