An influence of low-stability region on dense gas phenomena and their peculiarities in the ORC fluids

An influence of low-stability region on dense gas phenomena and their peculiarities in the ORC fluids

An existence of low stability region in the dense vapours and its influence on some peculiarities in behaviour of selected dry and isentropic ORC fluids is discussed. The retrograde phenomena in the flow of BZT fluids [1.] can be simply related to the mechanical and thermodynamic stability paramete...
