| Outline of Final Research Achievements |
Studies were conducted to promote scientific understanding on occurrence probability (explosion limit) and consequence (consequent damages) of gas explosions. About the explosion limit, it was found that the limit and its dependence on conditions can be appropriately predicted by considering adequate reaction scheme. About the consequence analysis, precious evaluation method of Markstein number, which is important to estimate flame front instability, has been newly developed. Also, it was found a large scale flame is propagating in self-similar manner and its flame area is growing in fractal manner. The mechanism of accelerating development of consequent damages can be understood. These results highly contribute to promote scientific predictions of gas explosion risks.
