ABSTRACT:
This disclosure is the use of high efficiency turbomachinery designs to achieve high efficiency thermodynamic cycles. The high efficiency thermodynamic cycles are referred to as the Modified Ericsson cycles, an expansion of the regenerative Brayton cycle. A Modified Ericsson cycle can include 2,3,4, or more stages (number of intercooling and heat/reheat cycles between stages) that achieve higher efficiencies and power density (net output power/cycle weight flow rate) than those of regenerative and nonregenerative Brayton cycles. Also included is a high temperature tip-turbine driven compressor design for Brayton, Modified Ericsson and other power/refrigeration cycles.
