Wave Rotor Technology For Gas Turbine Enhancement

Wave rotor technology has been in its development
stages for more than a century now. The complexity of
wave propagation and the computational challenges
were some of the biggest reasons the technology
did not gain prominence. Recent advancements in
controls, increased research in wave phenomenon and
improved computational power has rejuvenated this
fascinating technology. In the quest for improving
the efficiency of power generation devices while
keeping emissions low, wave rotors have a bright future.

Wave rotors are energy exchange devices that transfer
energy between two media. This body of research is
focused towards the efficient design of a viable
porting to be used on a test rig for gas turbine
enhancement. The first part of this research involves
a 1-D algebraic code developed at MSU to provide a
porting geometry for any given operating condition
while estimating the amount of Exhaust Gas
Recirculation. The code was benchmarked using two
commercial codes, GT-POWER and a 2-D computational
fluid dynamic code, FLUENT. The second part of this
work deals with the future developments of wave
rotors and the innovative designs that can be used to
improve this technology.
