• Development of a Diaphragm Stirling Cryocooler

      Caughley, A; Sellier, M; Tucker, A; Gschwendtner, M (International Cryocooler Conference, 2014)
      Callaghan Innovation, formerly Industrial Research Ltd, has developed a novel free-piston Stirling cryocooler concept using metal diaphragms. The concept uses a pair of metal diaphragms to seal and suspend the displacer ...
    • Development of a high frequency pulse tube

      Emery, N; Caughley, A; Glasson, N; Tucker, A; Gschwendtner, M (Scholarly Materials And Research @ Georgia Tech, 2010)
      A single-stage pulse tube cryocooler has been designed and fabricated to provide cooling at 50 K for a high temperature superconducting magnet. Sage software was used to design the pulse tube, with a predicted 25 W of ...
    • Development of a solar-powered liquid piston Stirling refrigerator

      Langdon-Arms, S; Gschwendtner, M; Neumaier, M (Elsevier, 2017)
      The objective of this research project is to develop a solar-powered refrigerator in the lower capacity range of up to 5 kW of cooling power. With the use of liquid pistons and one of the most efficient thermodynamic cycles ...
    • Modelling the performance of a Diffusion Absorption Refrigeration System

      Yousuf, N; Biteau, E; Anderson, T; Gschwendtner, M; Nates, R (Australian PV Institute (APVI), 2014)
      The diffusion absorption refrigeration cycle was first identified nearly a century ago but until relatively recently its application had been limited to niche cooling applications such as camping refrigerators. The diffusion ...
    • Novel diaphragm based stirling cryocooler

      Caughley, AJ; Tucker, A; Gschwendtner, M; Sellier, M (American Institute of Physics, 2012)
      Industrial Research Ltd has developed a unique diaphragm-based pressure wave generator technology for employment in pulse tube and Stirling cryocoolers. The system uses a pair of metal diaphragms to separate the clean ...
    • Novel parameter-based flexure bearing design method

      Amoedo, S; Thebaud, E; Gschwendtner, M; White, D (Elsevier, 2016)
      A parameter study was carried out on the design variables of a flexure bearing to be used in a Stirling engine with a fixed axial displacement and a fixed outer diameter. A design method was developed in order to assist ...
    • Performance of a Cooling System Driven by Engine Exhaust Heat

      Yousuf, N; Anderson, T; Gschwendtner, M; Nates, R (International Institute of Refrigeration, 2016)
      The use of stationary generators for electricity generation is widespread in areas where access to power distribution networks is limited, including rural areas and in developing countries. Often, a significant portion of ...
    • Predicting the Pumping Characteristics of Multiple Parallel Tube Air-lift Pumps

      Yousuf, N; Anderson, T; Gschwendtner, M; Nates, R (Australasian Fluid Mechanics Society, 2016)
      Air-lift pumps have begun to receive a high degree of attention due to the absence of mechanical components and the potential for their use in renewable energy applications. One of the principal challenges of the air-lift ...
