Large-scale instabilities in a STOVL upwash fountain [PDF]
, 2005 The fountain flow created by two underexpanded axisymmetric, turbulent jets impinging on a ground plane was studied through the use of laser-based experimental techniques. Velocity and turbulence data were acquired in the jet and fountain flow regions

Deep Underground Science and Engineering, Volume 4, Issue 3, Page 498-510, September 2025.Different failure modes observed in Tishreen tunnel include Floor heave, wall spalling, crashing of slab, and lining convergence reaching the failure limit. Abstract Squeezing phenomena can lead to severe loads in deep tunnels, especially in the presence of a low ratio of surrounding rock strength to overburden pressure.

Droplets formation inside a venturi liquid mixer [PDF]
, 1997 The formation of a coarse photographic emulsion by entraining a hot oil phase into a cooler aqueous phase by a Venturi device is considered. The main focus is on understanding the mechanism and site of droplet formation in the device, as well as the time-

Advanced Materials, Volume 37, Issue 34, August 28, 2025.The structural‐colored tube is created from cholesteric liquid crystal elastomers, exhibiting uniform color changes with high strain sensitivity upon extension and inflation. The color change occurs across multiple mechanochromic modes, highlighting the influence of molecular anisotropy and tubular geometry on strain sensitivity.

steel research international, Volume 96, Issue 8, August 2025.This study explores using DC plasma torches with nitrogen as a carrier gas for preheating large steelmaking ladles. Numerical models simulate ladles preheated by 0.7 and 1.5 MW plasma torches, compared to natural gas heating. Results show plasma torches achieve significantly higher bottom temperatures, validated by industrial measurements on full‐sized

Effects of vibrational nonequilibrium on the inviscid design of an axisymmetric nozzle for hypersonic flow [PDF]
An axisymmetric, hypersonic nozzle for arc-heated air is described. The method of characteristics is used to compute an inviscid nozzle contour in which vibrational nonequilibrium is approximated by the sudden-freeze technique.
