Abstract: Static thermomagnetic generators have a promising prospect in harvesting low-grade thermal energy for their structural simplicity, high reliability, and other advantages. However, the heat capacity of thermomagnetic materials, which will result in useless heat absorption, hinders it from achieving effective power generation. To address this issue, a static thermomagnetic generator adopting oscillating flow heat transfer was proposed in this paper. The unique regeneration design may well decrease the load of the heat exchangers dramatically, therefrom improve the overall thermal efficiency. The structure of the regenerative static thermomagnetic generator was introduced firstly, then the mechanism of regenerative heat transfer was unveiled in detail, and the dependence of heat transfer and regenerative performance on the flow channel dimensions and operating parameters was investigated theoretically and numerically. According to the calculations, the heat transfer performance increased with the dimensionless buffer-tube length and dimensionless fluid-flow amplitude while the regenerative performance deteriorated with increasing dimensionless fluid-flow amplitude. Further numerical study indicates that low frequency improves the heat transfer and regenerative performance significantly. At a frequency of 0.2Hz, the novel design shows an increase in thermal efficiency by a factor of 1.5 compared with the conventional configuration. However, the regenerative performance is far from its theoretical limit, much work remains to be done to improve it further.
