This paper reports a study on the use of an in-house 3D printed bi-directional turbine for energy conversion in a standing wave thermoacoustic environment that is operated at atmospheric pressure. The-3D printed turbine was placed at two locations along the resonator and the data were recorded over a range of flow frequency and flow amplitude. It is found that maximum output is achieved when the flow is not at resonance. Resonance of the standing wave inside the rig was found at 106 Hz but the bi-directional turbine performs better at a lower frequency of 85 Hz.
