A review presentation for master thesis was held in 14, Feb.2022.

Mr. Masato Nakazawa who is member of our lab presented research result entitled as "Study on the Ignition Characteristics of Propane/Air Mixture Impinging on a Heated Surface". In this study, we found the critical ignition condition of flowing propane/air mixture impinging on a hot surface heated by a constant power based on a series of experiment, numerical simulation, and dimensional analysis. It can be applied following practical situations; for example, to ignite the engine efficiently, to make the temperature boundary layer thicker is effective. To control ignition to prevent fires and explosions, to make it thinner is effective. We believe that we achieved very useful results in terms of combustion engineering and safety engineering.
