[1] The transport, mixing, and three-dimensional evolution of chemically distinct air masses within growing baroclinic waves are studied in idealized, high-resolution, life cycle experiments using suitably initialized passive tracers, contrasting the two well-known life cycle paradigms, distinguished by predominantly anticyclonic (LC1) or cyclonic (LC2) flow at upper levels. Stratosphere-tropos...

An ejector expansion transcritical CO2 refrigeration cycle is proposed to improve the COP of the basic transcritical CO2 cycle by reducing the expansion process losses. A constant pressure mixing model for the ejector was established to perform the thermodynamic analysis of the ejector expansion transcritical CO2 cycle. The effect of the entrainment ratio and the pressure drop in the receiving ...

Developments for air cycle systems with respect to special requirements concerning the use of compression and expansion machines for transport refrigeration are discussed in this paper. Historic aspects are mentioned briefly and the present situation in Germany is sketched in the example of an air cycle air-conditioning system for the new generation of the German high speed train ICE 2.2. In or...
