HEM and HRM accuracy comparison for the simulation of CO2 expansion in two-phase ejectors for supermarket refrigeration systems

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1422508

In this study, the accuracies of the homogeneous equilibrium (HEM) and homogeneous relaxation models (HRM) were compared. Both models were implemented in the ejectorPL computational tool. The HEM and HRM were used to simulate the carbon dioxide flow in ejectors that were designed for supermarket ref...

Full-scale multi-ejector module for a carbon dioxide supermarket refrigeration system: Numerical study of performance evaluation

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1453307

The performance of fixed ejectors installed in a multi-ejector module in a carbon dioxide refrigeration system is discussed in this paper. To analyse the module operation, three-dimensional ejector models including the inlet and outlet collecting ducts were considered. The tests were performed for t...

Experimental analysis of the r744 vapour compression rack equipped with the multi-ejector expansion work recovery module

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1322336

A test facility for the experimental investigation of the R744 vapour compression rack equipped with a multi-ejector expansion work recovery module was designed and manufactured. A comparison of the R744 multi-ejector refrigeration system with the R744 parallel compression system at the same test fa...

CFD-based shape optimisation of a CO2 two-phase ejector mixing section

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1296309

In this study, the geometry of a CO2 ejector mixing section was optimised. Two optimisation algorithms, a genetic algorithm (GA) and an evolutionary algorithm (EA), were used with a validated CFD model based on the homogeneous equilibrium model (HEM). The ejector was designed to increase the Coeffic...
