AB  - A  spatially-lumped dynamic model  of  a  reciprocating-piston  expander  is  presented  in  this  paper.  The  model accounts for the three main loss mechanisms in realistic piston machines, namely: pressure losses through the intake  and  exhaust  valves,  heat  transfer  between  the  gas  and  the  surrounding  cylinder  walls,  and  the  mass leakagebetween the compression/expansion chamber and the crankcasethrough the piston rings. The model also accounts for real-gas effects with the fluid properties calculated from the NIST database using REFPROP. The numerical calculations are first compared with experimental pressure-volume-temperature data obtained on a  custom  reciprocating-piston  gas  spring  over  a  range  of  oscillation  frequencies.  The  comparison  between numerical  and  experimental  results  shows  good  agreement.  It  also allows  the  most  accurate heat  transfer correlationto be selectedfor calculating the gas-to-wallin-cylinderheat transfer. The semi-heuristic modelling tool  is  thenused  to  design  an  expander  forspecific  pressure  ratiosand  mass  flowrate,  and  to  predict  the thermodynamic performance of the piston device over arange of part-load conditions.
