STUDIES FOR A NEW HOT AIR ENGINE. PART-II

Abstract

The second part of the Thermodynamic Analysis for a New Hot Air Engine is devoted to an investigation into the effects and advisability of subdividing compression and expansion into stages, with cooling or heating applied respectively between two stages. The requirements of combustion air are considered and the behaviour of the plant at part-load for several governing methods are discussed. In the conclusions the broad principles for a design as emanating from the analytical treatment are worked out, and suggestions are made for a suitable design of simple manufacture and operation. After an assessment of the advantages and limitations of the hot air engine suggestions are put forward for further investigating fundamental data on which a future design can be based which would ensure reasonably favourable operation.
