Because a shockwave over atmospheric pressure causes overpressure
, it can be lethal to humans and can result in severe disorientation similar to the effects of alcohol intoxication.
Gene expression for structural proteins was measured in mixed cell samples at 24 and 48 hours post overpressure
(a) Linearly decaying overpressure
time-history with zero rise-time (Figure 3, (8)),
Their pressure drop is usually a factor of the face velocity across them and the overpressure
they are protecting against.
 performed CFD simulations to analyze the effects of ignition location and vent area fraction on explosion overpressure
in chemical process plants.
The research group established a free-space explosion model and extracted the simulation results of the overpressure
peak value at the measurement point of the shock waves and then compared the values with those of the commonly used free-space explosion overpressure
empirical formula [23, 24]; the results show that the simulation result of the overpressure
peak value at the measurement point of the shock waves is consistent with the variation trend of the empirical formula result and is most similar to the calculated result of Henrych's empirical formula .
has a different scaled distance than normal ground vibration, where air overpressure
scaled distance is:
solutions encompass roots blowers and side channel blowers.
Welded to the connection piece of the measuring device at one end and to the tube end piece at the other end, the measuring systems are checked for leaks and undergo an overpressure
cycle to eliminate tensions in the material.
