Numerical and Experimental Analysis of Two Phase Flow in Ejector [PDF]

, 2014
When the ejector was applied in the natural gas exploitation and sea water desalination industries, the ejector always operated on the two phase operation, because of the primary fluid or the induced fluid usually companying some water inside.

Analysis and Optimization of Exergy Flows inside a Transcritical CO₂ Ejector for Refrigeration, Air Conditioning and Heat Pump Cycles

Energies, 2019
In this study, the exergy analysis of a CO2 (R744) two-phase ejector was performed using a 1D model for both single and double choking conditions. The impact of the back pressure on the exergy destruction and exergy efficiencies was presented to evaluate

Sacrificial‐Layer‐Assisted Heat‐Affected‐Zone Suppression in Laser Patterning of PET for High‐Performance Flexible Devices

Advanced Functional Materials, EarlyView.
A removable sacrificial polymer layer engineers the thermal boundary condition during nanosecond laser ablation of PET, suppressing heat‐affected‐zone formation without relying on costly ultrafast lasers. This strategy enables deep, high‐aspect‐ratio trenches with no detectable heat‐affected zone, templating silver‐filled mesh electrodes with record ...

Patient‐Derived 3D Heart‐On‐a‐Chip Model of Dilated Cardiomyopathy With Embedded Bead‐Based Mapping of Tissue Contractility

Advanced Healthcare Materials, EarlyView.
A heart‐on‐a‐chip model of dilated cardiomyopathy is developed from patient‐derived induced pluripotent stem cells. The model recapitulates key disease phenotypes and enables functional assessment through integrated bead‐based tracking and pillar deflection measurements.

Numerical study on the impact of needle and dryness fraction on two-phase ejector performance under fixed/varied operating pressure

Case Studies in Thermal Engineering
This study investigates the effects of varying needle block degree (blockage area ratio of the primary nozzle throat) and dryness fraction (the ratio of gas mass to mass of two-phase mixture) within the primary and secondary flow on the performance of a ...
