     View Summary

    数値解析により,火災旋風の挙動におけるふく射伝熱の効果の有無を評価した。その結果,ふく射伝熱を1次元近似して熱流動場解析に導入しても、十分な精度を有することがわかった。またふく射伝熱解析の導入により温度分布は大きな影響を受けるものの、流動場は大きな影響を受けないことがわかった。

     View Summary

    数値解析により,火災旋風の発生予測と火災旋風の挙動におけるスケール効果の有無を評価した。その結果,火災旋風の発生しやすい熱源上の位置や移動方向を把握することができた。また熱源から生じる上昇流と気象現象として現れる横風の強さにスケール効果が存在し,旋回流の強さや火災旋風の持続時間に影響することがわかった。

     View Summary

    霧層内の熱交換、特に霧粒子による吸収及び散乱による減衰に着目して、霧層の生成から消滅までの一連の過程を、一次元平行平板モデルを用いて、ふく射-熱伝導複合伝熱解析にて行った。霧層の生成・消滅を実際の観測データと比較し、比較的良い一致が見られた。霧層の消滅は良く捉えられた一方で、生成に若干の差異が見られたのは、消滅が強い熱流束(日射)で起きているのに対し、生成は放射冷却による弱い熱流束で進行するためであると考えられる。 20th-22nd July 2015, Sapporo

    水蒸気を燃焼場に導入し、そのふく射の吸収・再放射による高効率加熱システムを提案した。また、実際に実験装置を製作し、水蒸気付与の影響を調べた。その結果、水蒸気を入れ過ぎると却って熱効率が低下すること、効率を高めるためには、最適な水蒸気濃度が存在することが明らかになった。 29th-31st July 2015, Okinawa
