Hobson, Garth V. Naval Postgraduate School (U.S.) Aeronautical Engineering Approved for public release; distribution unlimited. Approved for public release; distribution unlimited. Two recent computer programs, WRCOMP and ENGINE, by A. Mathur, were used to examine the performance to be gained by incorporating a wave rotor component in a turbofan engine with mixed exhausts. The programs were transferred to a VAX-2000 computer, extended, and test cases reported by A. Mathur were successfully reproduced. A comparison was made between ENGINE, in which real gas effects are accounted for, and ONX (by J. Mattingly) in which constant specific heats are used. The inclusion of real gas effects proved to have a significant impact on the predicted performance. An extension of Mathur's results was made by varying the overall pressure ratio in the wave-turbofan engine. Further cycle studies and experiments to measure wave rotor component performance are recommended. 2013-08-01T21:15:52Z 2013-08-01T21:15:52Z 1990-09 Thesis http://hdl.handle.net/10945/34929 This publication is a work of the U.S. Government as defined in Title 17, United States Code, Section 101.
