Tao Zhang,Yiming Jiang,Shiqi Wang,Xuhai Pan,Min Hua,Zhilei Wang,Qingyuan Wang,Yunyu Li,Juncheng Jiang +8 more
TL;DR: In this paper , the authors used the three-dimensional Large-Eddy Simulation (LES) model to simulate high-pressure hydrogen leakage in a confined space and investigated the effects of the leakage hole shape on the flow features, including the circle, square, and triangle.

Influence mechanism of alkaline environment on the hydration of hemihydrate phosphogypsum: A comparative study of various alkali
TL;DR: In this paper , the influence of various alkali on hydration and microstructure of hemihydrate phosphogypsum (HPG) was investigated. And the effect of alkaline environment created by different kinds of alkali including Mg(OH), NH 3 ·H 2 O, NaOH and Ca(OH) 2 with variable contents on HPG were investigated.

Recovery Behavior of the Macro-Cracks in Elevated Temperature-Damaged Concrete after Post-Fire Curing
TL;DR: In this paper , the authors identified the crack recovery behavior of fire-damaged concrete after post-fire curing and its relationship with the recovery of strength, and the results indicated that after being exposed to high temperatures, the interfacial crack was the main type of crack, and it could clearly be recovered by post fire curing.
