Numerical Optimisation of the Regenerator of a Multi-stage Travelling Wave Thermoacoustic Electricity Generator (2021)
Presentation / Conference Contribution
Kisha, W., & Hann, D. (2019, September). Numerical Optimisation of the Regenerator of a Multi-stage Travelling Wave Thermoacoustic Electricity Generator. Presented at 16th UK Heat Transfer Conference (UKHTC2019), Nottingham, UK

In a travelling wave thermoacoustic engine, the regenerator is the heart of the engine [1], where the thermal interaction between the working gas and the solid material takes place. Unlike the stack in standing wave engine, the regenerator is more of...
