00925njm 22002777a 4500 dc Santos Sánchez, María Jesús author Vega-Lozano, Eduardo author Merchán Corral, Rosa Pilar author García Ferrero, Judit author Medina Domínguez, Alejandro author Calvo Hernández, Antonio author 2018-03-19 [EN]A thermodynamic model for a Brayton-like microturbine in combination with a solar parabolic dish is analyzed in order to evaluate its efficiency under any ambient condition. The thermodynamic cycle is a recuperative Brayton cycle with internal irreversibilities in the recuperator, compressor and turbine and external losses associated to the heat transfers in the solar receiver, the combustion chamber, and the environment. All the irreversibilities have been taken into account in the model with home-software elaborated using Mathematicaâ. The model validation is done by comparison with results provided by Semprini et al. [1]. An analysis of hybrid and sunless performance is carried out for four different microturbine power outlets (30, 23, 15 and 7 kWe) and for four days of the year (corresponding to each season). The greenhouse emissions are also calculated for both off-design performance and for the four power output levels. Santos, M.J., Vega, E., Merchán, R.P., García, J., Medina, A., Calvo, A.
