Boundary layer effect turbine

Abstract

Described herein are embodiments of a boundary layer effect turbine and a hydrodynamic speed reducer. Described is a boundary layer effect turbine that utilizes the phenomena of the boundary layer to drive a turbine impeller that is made of a plurality of spaced disks oriented along a rotatable shaft. As operating fluid is directed over surfaces of the plurality of disks of the boundary layer effect turbine, energy is transferred from the fluid to the disks as a result of the adhesive and viscous properties of the fluid.

Description

RELATED APPLICATIONS[0001]The present application is a §371 national phase application filing of Application No. PCT / US2008 / 088687, with an international filing date of Dec. 31, 2008, and which claims priority benefit from U.S. Provisional Application No. 61 / 018,089, filed Dec. 31, 2007, the entire contents of both of which are hereby incorporated herein by reference.FIELD OF THE DISCLOSURE[0002]The present disclosure relates to a boundary layer effect gas microturbine for the purpose of producing a torque for mechanical work or to generate electric power.BACKGROUND OF THE DISCLOSURE[0003]Reciprocating internal combustion engines have long been used to replace man power with that of the machine. In these engines, a linear motion is imparted to one or more reciprocating pistons by compression and ignition of a mixture of fuel and air. The linear motion of the one or more pistons is converted to rotational motion by connection of a connecting rod to a crankshaft. The rotation motion i...
