On the other hand, the reflected shock wave decays faster under higher initial pressure conditions due to the faster flame propagation.
Unburnt gas temperatures of 800.0 K and 890.0 K are below and within the NTC regime of stoichiometric PRF0/air under the initial pressure.
The effects of zeolite catalysts and reaction conditions on the ring-shift isomerization of sym-OHP into sym-OHA were studied through experiments at 200 300°C under an initial pressure of 0.79 MPa N2 or H2.
The catalytic reactions were mainly conducted at 473 573 K for 0.15 8 h under an initial pressure of 0.79 MPa N2 or H2 using six catalysts: a hydrogen Y zeolite, a lanthanum ion-exchanged Y zeolite, a hydrogen mordenite, and three noble metal loaded mordenites.

The unit, charged with defending much of Iraq's southern border area, appears to have disintegrated under the initial pressure of the invasion.
To account the effect of initial pressure on pmax under different combustion mechanisms, a dimensionless pressure PR was introduced to denote the relative intensity of explosion.
Under the same initial pressure; when the equivalent ratio is closer to 1, the flame acceleration rate becomes larger, and the explosion pressure reaches the maximum value.
Furthermore, the polymerization of AN in scCO2 under different initial pressures especially under low pressure (<14 MPa) was studied.
In this paper, a new calculation model of the optimal initial pressure under off-design conditions has been put forward.
The experimental results also indicate that the possibility of detonation occurrence increases with increasing initial pressure under the same compression ratio.
