Crack measurement after thermal shock is usually considered as a replacement because real-time observation of experiments difficult to achieve. This paper presents an experimental approach for displaying cracking using oxygen-acetylene flame and high-speed imaging translucent ceramic. We capture the crack propagation process, calculate speed, discuss effect sample size heat flux on propagation,...

BACKGROUND Swift and adequate fluid loading is a cornerstone of septic shock therapy. Yet, careful assessment of volume responsiveness and volume amount during the resuscitation process is a prerequisite. Both overzealous initial fluid administration and late fluid overload are harmful and may be associated with increased mortality. MAIN BODY Static (i.e., central venous or pulmonary artery o...

The flow characteristics on a truncated cone with a cylinder were experimentally investigated in a Mach 5 flow with a Reynolds number 3.8 × 10, based on the cylindrical diameter. Two different truncation ratios of 0.5 and 0.7 were used. The incidence angle varied from -12 to 0 degrees with 3 degrees intervals to investigate the influence of the truncation ratio on the surface flow pattern. The ...
