Outline of Final Research Achievements

We focused on nonequilibrium gas flows (Knudsen layers) induced by the evaporation from porous surfaces and obtained the following results. (1) To realize the velocity distribution measurement of gas molecules evaporating from a liquid surface using the time-of-flight method, we developed a novel experimental technique to maintain a liquid-vapor interface in a vacuum environment for a long period. The use of a porous membrane with an adequate pore size can significantly suppress the collisions between gas molecules after the evaporation from the liquid surface. (2) Numerical techniques were developed to efficiently analyze evaporating gas flows from porous surfaces using the low-variance deviational Monte Carlo method.

Academic Significance and Societal Importance of the Research Achievements

細孔表面からの蒸発は,自然や工学応用の様々な場面において普遍的にみられる現象である.高精度な蒸発モデルを構築するためには,液面から蒸発した直後の気体分子の速度分布を把握することが望まれるが,技術的困難から信頼性の高い計測結果はこれまでに報告されていない.また,細孔表面のように複雑な形状からの蒸発による非平衡気体流れを取り扱うために,効率的な数値解析法が求められている.本研究で得られた成果はこれらの課題の解決につながるものであり,今後,細孔からの蒸発を利用した気化冷却デバイスの開発などへの応用が期待される.
