A shot in the cold: a new open regenerative cycle for heat-pumps and refrigerators
Haywood, D; Gschwendtner, MA (University of Rome “La Sapienza”, International Stirling Engine Conference (ISEC), 2003)Although Stirling heat-pumps and refrigerators offer the possibility of environmentally-friendly operation by using air as the refrigerant, the Coefficient of Performance (COP) of low-cost Stirling systems is only about ... -
CFD modelling of a diaphragm stirling Cryocooler
Gschwendtner, MA; Caughley, AJ; Sellier, M; Tucker, A; Caughley, AJ; Sellier, M; Tucker, A; Gschwendtner, MA (Cryogenic Society of America, 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 ... -
Experimental investigation of regenerator materials in Stirling-cycle machines
Gschwendtner, MA (Dept. of Mechanical Engineering, the University of Canterbury, 2002)No abstract -
Investigation of seal performance in a 4-α double-acting Stirling cycle heat-pump/refrigerator
Haywood, D; Raine, JK; Gschwendtner, MA (International Stirling Engine, Universita de Roma, 2001)Concerns about the environmental impact of refrigerants used in vapour-compression heatpumps and refrigerators, have prompted the Stirling-Cycle Research Group at the University of Canterbury to investigate the feasibility ... -
Investigation of several novel kinematic mechanisms for Stirling-type machines
Gschwendtner, MA (Department of Mechanical Engineering, University of Canterbury, 2003)No abstract -
Optical investigation of the heat transfer from a rotating cylinder in a cross flow
Gschwendtner, MA (Springer, 2004)The heat transfer from a rotating cylinder in an air-cross flow was investigated by purely optical measuring techniques. Flow velocities were measured by a two-dimensional LDV both in the vicinity of the cylinder and in ... -
Some insights into Stirling machine behaviour
Tucker, AS; Gschwendtner, MA; Haywood, D (Georgia Institute of Technology, ICC Press, 2010)Through its involvement in the analysis, design and development of both Stirling engines and refrigerating applications, the Stirling Cycle Research Group at the University of Canterbury has, over several years, encountered ... -
Stirling-cycle heat-pumps and refrigerators – a realistic alternative?
Haywood, D; Raine, JK; Gschwendtner, MA (Institute of Refrigeration, Heating & Air Conditioning Engineers (IRHACE), 2002)Concerns about the environmental impact of refrigerants used in vapour-compression heatpumps and refrigerators, have prompted the Stirling-Cycle Research Group at the University of Canterbury to investigate the feasibility ... -
The development of a Vuilleumier Cryocooler for New Zealand’s high temperature superconductor industry
Gschwendtner, MA; Tucker, AS (CryoCooler.org, 2008)A Vuilleumier cryocooler with a projected cooling capacity of 100 W at 77 K has been developed at the University of Canterbury in New Zealand. While most cryocoolers use mechanical compressors with associated vibration, ... -
The Eckert number phenomenon - an experimental investigation of the heat transfer from a rotating cylinder in a cross-flow
Gschwendtner, MA (Macmillan (India), 2006)The Eckert number phenomenon describes a reversal in heat transfer from a moving wall at an Eckert number Ec ≈ 1. In this report the Eckert number phenomenon is confirmed experimentally for the first time. For that purpose ... -
The Eckert number phenomenon: experimental investigations on the heat transfer from a moving wall in the case of a rotating cylinder
Gschwendtner, MA (Springer-Verlag, 2004)The Eckert number phenomenon was investigated theoretically by Geropp in 1969 and describes a reversal in heat transfer from a moving wall at an Eckert number Ec ≈ 1. In this report the Eckert number phenomenon is confirmed ...
