MALAVER DE LA FUENTE, M.. Back Work Ratio of Brayton Cycle. Ing. invest. y tecnol. [online]. 2010, vol.11, n.3, pp.259-266. ISSN 2594-0732.

This paper analizes the existing relation between temperatures, back work ratio and net work of Brayton cycle, a cycle that describes gas turbine engines performance. The application of computational soft ware helps to show the influence of back work ratio or coupling ratio, compressor and turbine in let temperatures in an ideal thermodynamical cycle. The results lead to deduce that the maximum value reached in back work ratio will depend on the ranges of maximum and minimal temperatures of Brayton cycle.

Keywords : Brayton cycle; thermodynamical cycle; compressor; work retrocession relation; turbine gas; net work.
