Wave rotor technology has been in its development stages for close to a century now. The complexity of the wave phenomenon and the computational difficulties were some of the biggest reasons why the technology hasn't gained prominence. Recent advancements in controls, increased research in pressure waves 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 essentially 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. In the first part of this research, an algebraic code developed at MSU is described which can 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, a one dimensional code GT-POWER and a two dimensional computational fluid dynamic code, FLUENT. The agreement between the codes shows the strength of the 1D algebraic code and how it can be used for the preliminary development stage. 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.The rotor studied at MSU was the CX-93 which was taken from a Mazda 626 Capella 2.0 litre diesel engine. 2.2 FLOW ... The horizontal axis for the flow configuration diagrams is the rotor axial length while the vertical axis is time. The rotoranbsp;...
