Study on high-speed water entry process of non-rotating vehicles

Xibei Gongye Daxue Xuebao, 2023
The non-rotating trans-media vehicle can better adapt to the hypersonic flight conditions, but new problems in the hydrodynamic characteristics and motion stability arise during the water entry process.

Estimation of combustion efficiency range and pressure fluctuation at low working condition

Energy Reports, 2022
The exact data of combustion efficiency are rare in the open literature near the ignition and at sub-idle, especially at the state close to the lean blowout limit, due to the complexity of combustion characteristics and inconvenience of measurement in ...

Numerical study on the influence of floating ice on the water-exit hydrodynamic characteristics of a trans-media vehicle

Journal of Physics: Conference Series, 2023
Abstract In low-temperature combat conditions, the strong interference of floating ice on the water-exit process of trans-media weapons must be considered. The evolution of the cavity shape, hydrodynamic and ballistic characteristics during the water-exit process of a high-speed vehicle penetrating water (without floating ice) and ice ...

Endothelium trans differentiated from Wharton's jelly mesenchymal cells promote tissue regeneration: potential role of soluble pro-angiogenic factors. [PDF]

PLoS ONE, 2014
Mesenchymal stem cells have a high capacity for trans-differentiation toward many adult cell types, including endothelial cells. Feto-placental tissue, such as Wharton's jelly is a potential source of mesenchymal stem cells with low immunogenic capacity;
