Public Abstract	Researchers at Purdue University have developed a new system for reconstructing non-uniform circumferential flow fields in turbomachines. Gas turbine engines provide power to airplanes and ships. In these turbomachines, upstream stators operate machine blades and often unintentionally disturb flow as well as pressure and temperature by inducing mechanical vibrations. This can cause system stalling which can lead to permanent gas turbine engine damage. Probe technologies are being used to detect lags and disturbances in a machine's cadence but are often expensive and have difficulty accurately detecting fluctuations, often providing delayed warning signals. Purdue researchers have created a system that can calculate optimal locations to place low-cost, non-invasive probes in turbomachinery. The system can use the data collected by the probes to reconstruct a flow field and send a reliable, timely warning alert if harmonic rhythms are disrupted. In addition, the customizable algorithms developed by Purdue researchers are adaptable between different machines. Enhanced circumferential flow is achievable for turbomachines including gas turbines, windmills, and hydraulic turbines.
