A Consideration on the Flow of Steam in Steam Turbines.
Journal of the Society of Mechanical Engineers, 1941 多段落衝動タービンの相隣れる段落に於て、前段落の羽根より流出する蒸汽の有する速度エネルギの利用問題を中心として、タービン内における蒸汽の流動を取扱つた。就中低圧部で相隣れる二つの段落の間隙が可なりあり、且両段落の平均羽根円直径に急変を與へる場合をとつて、かゝる構造の汽室内に運轉状態の如何によつて起ることあるべき蒸汽の種々の流動状態を近似的計算によつて解析した。そして如何なる設計にすればかゝる特殊構造の段落のノズル效率を増進し、且その特性を改善し得るかを論じた。

Advanced Science, EarlyView.KFO‐Atlas reveals how real‐world aromas are organized as structured mixtures rather than individual molecules. Building on these principles, KFO‐Gen, a generative AI framework, designs perceptually valid aroma formulations and reconstructs meat‐like aromas exclusively from plant‐derived odorants, providing a foundation for mixture‐level studies and AI ...

Systematic Investigation on Conjugate Heat Transfer Rates of Film Cooling Configurations
International Journal of Rotating Machinery, 2005 For the determination of the film-cooling heat transfer, the design of a turbine blade relies on the conventional determination of the adiabatic film-cooling effectiveness and heat transfer conditions for test configurations.

MN•CS•IO System: Cross‐Species Study for HBB Function in High‐Altitude Hypoxia Adaptation
Advanced Science, EarlyView.We developed an integrative mesh‐nanorod sorting, chitosan nanoparticle delivery, and intraosseous injection (MN•CS•IO) system to investigate HBB in high‐altitude hypoxia adaptation. Transplanting Tibetan animals' HBB‐modified Lin‐ cells into mice achieved 95.59% transfection efficiency and 8.15% HBB expression. High‐altitude HBB recipients upregulated

Steam drum design for direct steam generation [PDF]
AIP Conference Proceedings, 2017 For the direct steam generation in solar fields, the recirculation concept has been demonstrated in several installations. Water masses in the solar field vary during transient phases, such as passing clouds. The volume of the steam drum can serve as a buffer during such transients by taking in excess water and providing water storage.
