A NEW VAPOR GENERATOR DESIGN FOR RANKINE CYCLE ENGINES

The paper describes a new vapor generator design for use in automotive Rankine Cycle engines. The unit consists of a rotational preheater/boiler combined with a monotube superheater. Steady-state heat transfer and stress limitations are discussed. A dynamic model of the system is also presented. It is demonstrated that the gas side heat transfer can be improved with the addition of fins and, that from a stress standpoint, realistic materials, weight, and dimensions are possible. The transient thermal response characteristics are significantly improved over the vapor generator designs currently under consideration. /GMRL/
