“…For a low power-output system (<1 kW) such as this, positive-displacement expanders may be favoured over turbomachines (as discussed Section 1.2). Thus, for all simulations, an isentropic efficiency of 75% is used which is typical of those reported for small-scale positive-displacement machines [10,25,[30][31][32][33][34][35]. The pressure at the expander exit is set to be equal to the saturation pressure at State 1 (see Section 2.2.3).…”

“…Available options of volumetric expanders include reciprocating and rotary expanders, but this last solution, which is often based on the Wankel concept [2,4], shows implementation difficulties [1], while reciprocating SEs result in an easier design and construction [5].…”

“…The use of small-scale Water Steam RCs that are characterised by a small steam flow rate, shifts the expander technology from turbomachines towards volumetric machines [2], since some of the major problems of using turbines as expanders in small-scale RCs are their very low efficiency, high production costs, especially for multistage turbines, and the possibility of a rapid erosion of the turbine's blades due to the moisture content in the expanding steam [3].…”

“…Of the positive-displacement expanders, common designs include rotary-vane expanders with reported isentropic efficiencies that range from 25% to 35% [9], helical screw expanders with reported isentropic efficiencies that range from 30% to 85% [9,10], and scroll expanders with reported isentropic efficiencies that range from 30% to 70% [11]. The research performed in this investigation pertains to quantitatively understanding the performance of a novel form of expander.…”
