Impact of built-in and actual expansion ratio difference of expander on ORC system performance

Built-in expansion ratio is set with screw expander design, influenced by the geometric shape, size, and flow characteristic. Actual expansion ratio, which equals to the evaporation pressure divided by the back pressure of discharge line, is determined by operating conditions. In the previous ORC sy...
