Compressed air energy storage
圧縮空気エネルギー貯蔵は、地下の空気圧縮を利用して、効率的なエネルギー管理とピーク需要への対応を実現する。

圧縮空気エネルギー貯蔵(CAES)は、余剰の電気エネルギーを機械的な位置エネルギーに変換する技術であり、地下の地質構造(塩洞窟、帯水層、多孔質岩石貯留層など)に空気を圧縮して蓄え、需要のピーク時に膨張タービンを通して回収する。

熱力学 性能は、圧縮・膨張段階、中間冷却、熱回収、蓄熱システムの統合に大きく依存し、往復効率が大きく異なる断熱、非断熱、等温の各方式が区別されます。貯蔵媒体の地質力学的健全性、坑井の密閉性、空洞からの浸出プロセスが、長期的な運用可能性を左右します。現在の研究では、燃焼を完全に排除する高度な断熱構成、エクセルギー損失を低減する等温方式、および系統運用最適化を目指しています。

A CFD&ndash;DEM Numerical Study

Published on 2026-01-29 by Weiqiang Zhao, Xijie Song, Ning Wang, Yongyao Luo, Ling Ma @MDPI

Abstract: During the discharge process of a salt cavern compressed air energy storage (CAES) system, high-speed air flow may entrain salt slag from the cavern floor, posing a threat to pipeline safety. Currently, there is a lack of in-depth research into the transient mechanisms of the entrainment process, particularly the influence of particle shape. This study employs a CFD-DEM coupling approach to conduct, for the first time, a high-fidelity simulation of slag entrainment dynamics during the initial di[...]

Normal Shock Wave Approximations for Flight at Hypersonic Mach Numbers

Published on 2026-01-24 by Pasquale M. Sforza @MDPI

Abstract: Normal shock pressure ratios in equilibrium air for Mach numbers up to 30 and altitudes to 300,000 feet are shown to be correlated by a simple power law which provides an accuracy of &amp;plusmn;2%, thereby permitting direct calculation of corresponding enthalpy ratios accurate to &amp;plusmn;1% without iteration; a slight change in power-law coefficients extends this capability to Mach 65. Temperature, density, and compressibility may be then found directly from tables for high temperat[...]


Our summary: The study presents a power law correlation for normal shock pressure ratios in equilibrium air at hypersonic Mach numbers. It enables accurate calculations of enthalpy ratios and other state variables without iteration.
