PERFORMANCE ENHANCEMENT OF A MINIATURE STIRLING CRYOCOOLER WITH A MULTI MESH REGENERATOR DESIGN [PDF]

open access: yesJournal of Engineering Science and Technology, 2017
A parametric study has been carried out using the software REGEN 3.3 to optimize the regenerator of a miniature Stirling cryocooler operating with a warm end temperature of 300 K and cold end temperature of 80 K.

Cryogenic Thermomechanical Compressor [PDF]

open access: yesProblems of the Regional Energetics, 2023
The purpose of this work is to create a compact supercharger to provide circulation of protective gas medium in a closed circuit. It was proposed to use a thermomechanical compressor to achieve this purpose.

Liver regeneration [PDF]

open access: yesJournal of Cellular Physiology, 2007
AbstractLiver regeneration after partial hepatectomy is a very complex and well‐orchestrated phenomenon. It is carried out by the participation of all mature liver cell types. The process is associated with signaling cascades involving growth factors, cytokines, matrix remodeling, and several feedbacks of stimulation and inhibition of growth related ...

Numerical investigation on a travelling wave thermoacoustic heat pump

open access: yesJournal of Thermal Science and Technology, 2018
A thermoacoustic heat pump heater is a device having the ability to produce heat from acoustic power. The heat pump investigated was composed of an acoustic driver, a branched tube, and a looped tube.

Using a side-branched volume to tune the acoustic field in a looped-tube travelling-wave thermoacoustic engine with a RC load [PDF]

open access: yes, 2017
Travelling-wave thermoacoustic engine utilises a compact acoustic network to obtain a right time-phasing between the acoustic velocity and pressure oscillations within the regenerator to force gas parcels to experience a Stirling-like thermodynamic cycle.

Performance investigation of a high-field active magnetic regenerator

open access: yesApplied Energy, 2019
Regenerative magnetic cycles are of interest for small-scale, high-efficiency cryogen liquefiers; however, commercially relevant performance has yet to be demonstrated. To develop improved engineering prototypes, an efficient modeling tool is required to

Improvement of technical performance of heat regenerator of GPU-3 Stirling engine

open access: yesEnergy Reports, 2023
In this paper, in order of simulate the performance of Stirling engine a novel adiabatic model (irreversible adiabatic) is proposed for the Ground Power Unit Stirling engine, which has higher accuracy than previous models of this Stirling engine.

Sex and Regeneration [PDF]

open access: yesBiology, 2021
Regeneration is usually regarded as a unique plant or some animal species process. In reality, regeneration is a ubiquitous process in all multicellular organisms. It ranges from response to wounding by healing the wounded tissue to whole body neoforming (remaking of the new body).
