Design and Optimization of a Novel Kalina‐Organic Rankine Cycle System Based on LNG Cold Energy Utilization

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study proposes a novel integrated system (SDKC‐DORC) that combines a split‐flow dual‐pressure Kalina cycle with a secondary organic Rankine cycle for the synergistic utilization of solar energy and liquefied natural gas (LNG) cold energy.

ERRATA:Diagnostic Technique for Degradation of Engineering Materials by Measurement of Thermophysical Properties

Netsu Bussei, 2007
工業材料は表面に多数の微視き裂が発生する劣化初期段階で表面層のみかけ熱伝導率が変化する。熱物性のその場測定技術により、その熱伝導率変化から劣化の度合いを評価、診断する方法を開発した。この微視き裂層が存在する場合について、固体熱物性テスターによる温度応答および熱伝導率測定値に対する影響を理論的に検討した。この理論を検証するために金属材料を用いて疲労試験を行い、試験前後での材料表面と熱伝導率の変化を比較検討した。その結果、それらの熱伝導率減少度から劣化評価パラメータの推算が可能であることを確認した。

Influence of Wall Deformation Structure on the Liquid Film Flow Behavior Under Turbulent Conditions

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT To explore the influence of typical wall deformation structure in the scrubbing‐cooling tube on the liquid film, this paper studied the liquid film flow behavior on the riblet walls with representative riblet radii and compared them with the flat wall. Under different liquid film Reynolds numbers (Rel = 8.3 × 103 ~ 3.14 × 104), the liquid film

Research on Evaporation Characteristics and Safe Storage Duration of Marine Liquid Hydrogen Storage Tanks Under the Coupling Effect of Heat Leakage and Sloshing

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Liquid hydrogen, a zero‐carbon and high–energy‐density fuel, is a promising option for future oceangoing vessels. During maritime transportation, onboard cryogenic tanks are exposed to ambient heat leakage and ship‐induced roll motion, which can trigger sloshing and fundamentally modify the coupled thermo‐fluid processes governing boil‐off and
