Thermodynamic and turbomachinery design analysis of supercritical Brayton cycles for exhaust gas heat recovery
(Elsevier Ltd., 2018-11-01)
Significant amount of energy is wasted in engine systems as waste heat. In this study, the use of supercritical Brayton cycles for recovering exhaust gas heat of large-scale engines is investigated. The aim of the study ...
Experimental study of small scale and high expansion ratio ORC for recovering high temperature waste heat
(Elsevier, 2020-07-11)
In recent times, the use and development of small-scale ( 10 kW) ORC systems has received an increasing interest. However, the operational characteristics of small-scale high-expansion ratio ORC turbines are not yet well ...
Design and verification of a hermetic high-speed turbogenerator concept for biomass and waste heat recovery applications
(Elsevier, 2020-09-11)
Many waste heat recovery and biomass applications offer opportunities for small-scale steam turbines to produce electricity and to improve systems’ energy efficiency. However, the currently used axial turbine-based technology ...
