The author has worked for several years on a new heat engine based on evaporative cooling of hot dry air at reduced pressure. In piston-in-cylinder format such engines will be large and slow-revving, and such an experimental engine was constructed recently by the author. The experiments provided a modest confirmation of the thermodynamic analysis.

Amongst the many losses that must be managed, one of the most significant is incomplete evaporation during the recompression stroke. A combined theoretical and numerical treatment of this issue will be described. The talk will conclude with a summary of prospects for successful development.
