Flash Evaporation in Cyclones

Flash processes have been investigated several times [1–4]. This study focuses on the flash process taking place in a cyclone. The separated and extracted steam expands directly into a cylinder of a piston engine. In contrast to known flash expanders, the pressure drops continuously within a short time. Of special interest is the efficiency of phase separation which is critical to the feasibility of the piston process with internal flash evaporation. The conversion of low temperature heat into mechanical and electrical power plays a major role in the field of renewable energies. A new triangle shaped thermodynamic cycle can achieve efficiency of such conversion that exceeds the efficiency of standard Rankine cycles. The most interesting subprocess is flash evaporation taking place in a cyclone.
