[Title of award-winning research]
ダ ブ ル D Study on induction heating equipment using a die coil as an auxiliary coil

[Details of award-winning research]
　Induction heating technology is used as a clean heat source that does not emit greenhouse gases during heating. However, the distribution of heat generated in an object to be heated, such as an iron plate, depends on the shape of the heating coil, and uneven heat distribution can cause the object to crack or warp.
　In this study, we investigated the heat distribution of a heating coil that combines a circular coil and two semicircular (double D-shaped) coils, with the aim of achieving uniform heating in an induction heating device for flat plates. In the presentation, we performed a simulation verification of heating unevenness between the coils and considered heating coil shapes that can reduce heating unevenness.
