Measurement of losses in a Stirling cycle cooler

Cryogenics, 1987
Abstract An attempt has been made to identify and measure all the significant power losses in a miniature Stirling cycle refrigerator. Methods of measuring these losses in a working refrigerator using non-invasive instrumentation are described. An energy balance is presented which shows that all the major sources of energy loss have been accounted ...

A Numerical Model for Stirling Cycle Machines

Journal of Engineering for Power, 1980
The further development of a model to accurately simulate the performance and detailed behavior of Stirling cycle machines is described. The transport equation set (which describe the working gas) is derived in both the so-called integral and differential forms. Only the integral equation set is solved for the simulation.

Application of Stirling Cycle Generators in Production Operations

CIPC/SPE Gas Technology Symposium 2008 Joint Conference, 2008
Abstract Clean, inexpensive, and reliable on-site electric power generation for remote wellsites is an emerging need. There is a growing demand for electric power sources in the range of ½ to 1.5 kW to run pumping units and pumps on liquid loaded gas wells.

Optimization of design parameters of Stirling cycle machine

Cryogenics, 1993
Abstract The performance of a Stirling cryocooler is governed by six principal design parameters, namely speed, pressure limits, the temperature of the working fluid in the compression and expansion spaces, the ratio of the compression and expansion space swept volumes, the ratio of total dead volume and expansion space swept volume and the phase ...

A Mathematical Model for the Stirling Engine Cycle

Journal of Engineering for Power, 1981
A mathematical model for the Stirling engine cycle is presented. This model differs from the Schmidt Cycle in that an adiabatic dead space is assumed and that the enthalpy exchange between various volumes is accounted for. The model, in general, predicts performance which is lower than the Schmidt Cycle.

Stirling-cycle cryocooler active vibration control

Proceedings of IEEE International Conference on Control and Applications, 2002
A cryogenic cooler capable of continuously maintaining the required cryogenic temperature is one of the critical elements enabling space-borne surveillance sensors to detect cold objects against a space background or warm objects against an Earth background.

Stirling’s cycle and the second law of thermodynamics

American Journal of Physics, 1984
In order to prove the general validity of the second law of thermodynamics, several instances of the Stirling cycle are studied, especially in relation to their efficiency.

New Analytical Model for Appendix Gap Losses in Stirling Cycle Machines

, 2014
This contribution presents a new enhanced modeling approach for appendix gap losses for Stirling cycle machines. According to recent findings, previously available models are based on too gross simplifications and require further refinement.
