Wave Rotors for Ultra-Micro Gas Turbines

IntroductionGas turbine engines are essentially simple devices having only three parts: a compressor, a combustion area, and a turbine. Applications of such engines are well know, for example, in jet engines of aircraft, propulsion systems of tanks, and small industrial power plants. Devices such as wave rotors have been used in an attempt to improve...

Hydroforming of Composite Materials

IntroductionIn hydroforming, a metal blank is formed into a desired shape with the use of fluid pressure impinging on the blank which in turn impinges on a die that gives the blank its final shape. Hydroforming has a number of advantages when compared to other shaping processes, including reduced tooling cost, increased drawability, and enhanced stability....

Radial Wave Rotor (Wave Disc)

IntroductionTraditional attempts to use depressions or pockets to control wave reflection of off-design operation in internal combustion engines undesirably reduce the sensitivity of axial wave rotors to engine speed changes. Nevertheless, there still exists a need to improve the performance and reduce the size of traditional wave rotors to enhance...

Novel Electroactive Polymer-based Flow Sensors for Automotive Systems

Description of TechnologyMichigan State University’s sensing technology enables potential commercial applications in a broad range of industrial applications where information is needed on a combination of fluid/gas flow rates (e.g., in a line), along with the real-time density/viscosity variation of those fluids or gases. The invention uses electroactive...
