Outline of Research at the Start

日本国内では毎年4万件の出火件数が報告されていて,出火原因1位は概ねたばこである.たばこが原因の出火に象徴されるように,燃焼の初期段階は固体の燻焼状態がしばらく続き,条件が揃うと有炎状態へ遷移する.一方,関東大震災の大火災においては火災旋風が原因とされているように,有炎火災は風と絡み合って被害を大きくする.本研究は「しばらく続く燻焼状態」を燻焼状態において燃焼前線を平面閉曲線として捉え,その界面方程式の解を追跡することによって理解し,「火災旋風に代表される有炎状態」を旋風と浮力によって強く揺らめく炎を非常に多くの空間曲線の集まりとして捉え,その運動方程式の解を追跡する方法によって理解する.

Outline of Final Research Achievements

The research topic is encompassed within the framework of the discipline of interface tracking by direct methods, and the core of the research is the exploration of the science of specific phenomena unique to combustion. Combustion is a phenomenon in which microscopic chemical reactions are visualized on a macroscopic scale. Inquiring into the nature of combustion phenomena means answering the questions of how far the microscopic phenomena are reflected in the macroscopic model equations, whether the parameters in the model equations are appropriately chosen, and whether the model equations can be analyzed quantitatively and qualitatively. The following results were obtained: basic modeling research on combustion phenomena, mathematical research to track the behavior of solutions to model equations, image processing research using experimental data, and combustion modeling of bellows-folded paper.
