The goal of this project was to design, construct, and commission a moving bar wake generator to enhance the quality of the experimental results for the existing linear compressor. The compressor stage flow model was improved by the addition of wake turbulence, simulating the wake shed by an upstream blade row. Existing compressor rigs were researched to determine appropriate design parameters, the linear cascade was modified to allow for the passing of bars, and the wake generator mechanism was constructed. A blade with pressure tappings was also designed for better assessment of the flow around the blades. With regards to commissioning the cascade, the necessary instrumentation was calibrated and the effectiveness of passive flow control was evaluated.
