Design Methodology for a Rankine Microturbine: Thermomechanical Analysis and Material Selection
2011
Journal of microelectromechanical systems
The Rankine microturbine is a microelectromechanical system being developed for generating mechanical and electrical power from waste heat, such as from automobile exhaust gases. The design of this device faces the difficult challenges of creating structures rotating at high-speeds (1 000 000 r/min), sustaining large internal pressures (3 MPa) and temperature gradients (100 • C/mm), and machining millimeter-sized components of ceramic or metallic materials with micrometer tolerances. Here, we
