Thermodynamic modelling and parameter determination of ejector for ejection refrigeration systems (2016)
Journal Article
Ma, Z., Bao, H., & Roskilly, A. P. (2017). Thermodynamic modelling and parameter determination of ejector for ejection refrigeration systems. International Journal of Refrigeration, 75, 117-128. https://doi.org/10.1016/j.ijrefrig.2016.12.005

This paper presents a detailed thermodynamic modelling method of an ejector for ejection refrigeration system. In this model, the primary flow in the ejector was assumed to fan out from the nozzle without mixing with the secondary flow in a certain d...

Chemisorption power generation driven by low grade heat – Theoretical analysis and comparison with pumpless ORC (2016)
Journal Article
Bao, H., Ma, Z., & Roskilly, A. P. (2017). Chemisorption power generation driven by low grade heat – Theoretical analysis and comparison with pumpless ORC. Applied Energy, 186, 282-290. https://doi.org/10.1016/j.apenergy.2016.01.022

Sorption cycles have been extensively developed for waste heat recovery to deliver cooling, heating, and electricity. Chemisorption cycles using metallic salts as sorbents and ammonia as working fluid have been explored in this work for the maximum p...
