  1. Modelling of a floating piston expander employed in a 10 K cryocooler

    Chaudhry, GunaranjanMassachusetts Institute of Technology2005

    … a counter-flow heat exchanger, and an expander to expand the working fluid. The work of the expanding cold gas is transmitted up a floating piston and is dissipated by gas flows in and out of a warm volume. Flow through the cold volume is controlled by smart electromagnetic valves. …

  2. Development of a floating piston expander control algorithm for a Collins-type cryocooler

    Hogan, Jake (Jake R.)Massachusetts Institute of Technology2012

    … Collins-type cryocooler uses a floating piston design for the working fluid expansion in each stage. The piston floats between a cold volume, where the working fluid is expanded, and a warm volume. The piston's motion is controlled by opening and closing valves connecting several …

  4. Contribution to the Characterization of Piston Expanders for Their Use in Small-scale Power Production Systems

    Oudkerk, Jean-FrançoisULiège - Université de Liège2016

    Piston expanders are well suited for small scale power generation (<50kW) using heat engines such as Ericsson engine or Organic Rankine Cycle (ORC) system. Both systems offer the possibility to use renewable energy sources and are increasingly considered in light of the economic and environmental …
