abstract = {The conventional design of organic Rankine cycle (ORC)
power systems starts with the selection of the working fluid
and the subsequent optimization of the corresponding
thermodynamic cycle. More recently, systematic methods have
been proposed integrating the selection of the working fluid
into the optimization of the thermodynamic cycle. However,
in both cases, the turbine is designed subsequently. This
procedure can lead to a suboptimal design, especially in the
case of mini- and small-scale ORC systems, since the
preselected combination of working fluid and operating
conditions may lead to infeasible turbine designs. The
resulting iterative design procedure may end in conservative
solutions after multiple trial-and-error attempts due to the
strong interdependence of the many design variables and
constraints involved. In this work, we therefore present a
new design and optimization method integrating working fluid
selection, thermodynamic cycle design, and preliminary
turbine design. To this purpose, our recent 1-stage
continuous-molecular targeting (CoMT)-computer-aided
molecular design (CAMD) method for the integrated design of
the ORC process and working fluid is expanded by a turbine
meanline design procedure. Thereby, the search space of the
optimization is bounded to regions where the design of the
turbine is feasible. The resulting method has been tested
for the design of a small-scale high-temperature ORC unit
adopting a radial-inflow turbo-expander. The results confirm
the potential of the proposed method over the conventional
iterative design practice for the design of small-scale ORC
turbogenerators.},
