| 摘要 | PURPOSE:To attain a thermal efficiency approximate to that of theoretical Carnot cycle, by causing a no-phase-change working fluid to flow through a passage of uniform cross-sectional area between a compressor and a turbine and by increasing the velocity of the fluid to be slightly lower than the Mach number of 1 as extenal heat is received. CONSTITUTION:A closed circuit comprises a compressor 5, a passage 7, a turbine 6 and another passage 8. The passage 7 has a uniform cross-sectional area. A working fluid, which does not undergo phase changes, is supplied wit external heat Q1 through the wall 9 of the passage 7 so that the velocity of the fluid is increased to be slightly lower than the Mach number of 1. The fluid performs adiabatic expansion on the turbine 6. In the passage 8, heat is taken off from the fluid and transferred to the outside through the wall 11 as shown by Q2. After that, the velocity of the cooled working fluid is increased beyond the Mach number of 1 and the fluid flows into the compressor 5. Since the kinetic energy obtained by the velocity increase is recovered in the compression process and the frictional heat on the passage walls 9, 11 is recovered, a high efficienty approximate to that of theoretical Carono cycle is attained. | ||||||
