Rotating Detonation Engine

Experimental Model with Cooling System

Two types of combustion exist: deflagration and detonation. The combustion we often see (candle flames, stoves, thermal power plants, car engines, etc.) is called deflagration. On the other hand, detonation is a phenomenon in which combustion propagates at supersonic speeds and is sustained by shock waves and chemical reactions. When this detonation phenomenon is used in a combustor, the theoretical thermal efficiency can be improved by more than 20% compared to a conventional combustor. However, due to the high heat load and difficulty in visualizing the internal phenomena, it has not yet been put into practical use. Therefore, our laboratory is engaged in combustion experiments of a rotating detonation combustor equipped with a water-cooling mechanism and fluid dynamics simulations, aiming for practical application through detailed analysis of internal phenomena from both experimental and simulation perspectives. We are also actively engaged in collaborative research with companies and have many opportunities to conduct experiments outside the university.
