The efficiency of expanders is of prime importance for various
clean energy technologies. Once mechanical losses (e.g. through
valves) are minimized, losses due to unsteady heat exchange between
the working fluid and ...
Reciprocating-piston devices can be used as high-efficiency
compressors and/or expanders. With an optimal valve design and
by carefully adjusting valve timing, pressure losses during intake
and exhaust can be largely ...
