Experimental and Computational Studies on Cryogenic Turboexpander
TL;DR: In this article, a modest attempt has been made at NIT, Ireland to understand, standardise and document the design, fabrication and testing procedure of cryogenic turboexpanders, and a clear understanding of the thermodynamic scenario though modelling, that will help in determination of blade profile, and prediction of its performance for a given speed and size.

Flow field analysis of high-speed helium turboexpander for cryogenic refrigeration and liquefaction cycles
TL;DR: In this paper, a three-dimensional transient flow analysis of a turboexpander for helium refrigeration and liquefaction cycles was performed using Ansys CFX®, to understand the flow field of a high-speed helium turboexpanders, which in turn will help in taking appropriate decisions regarding modifications of established design methodology for improved efficiency of these machines.

CFD Analysis of Turbo Expander for Cryogenic Refrigeration and Liquefaction Cycles
TL;DR: In this paper, 3D turbulent flow analysis of a cryogenic turboexpander for small scale air separation was performed using Ansys CFX®, and modifications and further analysis required to evolve a more robust design procedure, have been suggested.

Effect of rotation on the flow behaviour in a high-speed cryogenic microturbine used in helium applications.
TL;DR: In this paper, three-dimensional unsteady flow analysis of a high speed microturbine used in helium applications was carried out using Ansys CFX® and the loss generated by the various secondary and vortical flows for the different cases was quantified in terms of entropy loss coefficient.

Application of parallel heat exchangers in helium refrigerators for mitigating effects of pulsed load from fusion devices
TL;DR: In this paper, performance of a J-T stage as a part of modified Claude cycle based helium refrigerator has been analyzed subjecting it to a pulsed heat load for understanding of the behavior of the components.
