项目摘要
固液混相流や固気混相流における最適な攪拌・混合法を見つけることは, 化学装置やバイオリアクタ, あるいは鉄鋼炉の設計等において重要な指針を与える. 本研究では攪拌混合が比較的緩やかなTaylor vortex flow(TVF)に注目し, 微生物などの増殖率の増加効果や濾過装置への応用を視野に入れた流れの解析に主眼をおいた. TVFは単純な装置であり, 乱流へも段階的に遷移する(スペクトル遷移)ため, カオス混合など, せん断力に弱い微生物や細胞の効果的な混合法の開発に大きく発展すると思われるが, 未解明な点も多い.本研究では, アスペクト比が小さく(Γ=3), 上下境界端効果を有するTVFを用いて, その固液混合特性を可視化法, 並びに超音波流速分布計測法を用いて解析した. この結果, 渦モードによってカオス混合への遷移状況が大きく異なり, 渦自身が自励振動する場合や, 渦と渦の界面が振動する場合など, そのメカニズムが大きく異なることが明らかになった.また, このTVF装置を利用した光合成微生物増殖用バイオリアクタを試作し, 培養実験を行った. 光合成微生物が強いせん断流れによって破壊された場合の定量的な検出法を開発し, これを用いてTVFの効果を調べたところ, Re=30,000までの速い流れでも微生物は破壊されることなく順調に増殖した. ただし, Re>60,000では細胞破壊が検出される場合が観察され, 不安定な挙動を示した.
Solid liquid mixed phase flow and solid gas mixed phase flow are the most suitable agitation and mixing methods. Chemical equipment is important for the design of iron and steel furnaces. In this study, we focused on the slow mixing and mixing of Taylor vortex flow(TVF), the increase of microbial growth rate and the application of filtration equipment. TVF is a pure device, the turbulent flow of the stage of migration, mixing, breaking force, weak microorganisms and cells of the mixed method of development of large development, many problems have not been solved. In this study, the ratio of flow velocity to flow velocity is small (T =3), the TVF of upper and lower boundary effects is used, the solid-liquid mixing characteristics are visualized, and the ultrasonic velocity distribution measurement method is used to analyze. As a result, the vortex-vortex interface is vibrating, and the vortex-vortex interface is vibrating. This TVF device is used for photosynthetic microbial growth. Photosynthetic microorganisms were developed by quantitative analysis in the presence of TVF, Re=30,000, and the growth of microorganisms was regulated. In case Re>60,000, the cell breakdown is detected, and the instability is detected.
