ABSTRACT = {The scroll expander used in organic Rankine cycle (ORC) system is
improved, and its performance is analyzed experimentally. The modified profile
and inlet hole of the scroll expander are enhanced, and the performance of the
scroll expander before and after the improvement is analyzed. The results show
that when the inlet pressure exceeds 0.7 MPa, the waist-shaped hole with a larger
area is preferable. The scroll expander with a waist-shaped hole has a larger output power and wider optimal pressure range, and when the inlet pressure is
1.6 MPa, the maximum output power increases by 230 W. The output power
and isentropic efficiency of the scroll expander can be improved by modifying
the profile. When the inlet pressure is 1.6 MPa and the rotational speed is
1750 r/min, the maximum output power of the scroll expander is 1235 W, which
is 120 W higher than that before the improvement.},
