In this paper, a few of these results are shown in the form of extracted stills, with the aim to reveal the location and shape of the reaction zone at various stages of the flame development.
A comparatively thin layer has been observed for the WM model in comparison with the TPDF model where the reaction zone is more distributed due to the consideration of turbulent fluctuations within a cell.
Figure 11(a) shows a positive effect of flow velocities on RDFs, indicating that the reaction zone was gradually lifted with increasing flow velocities.
It is composed of several reaction zones (Figure 3), which are described as follows: (1) grey color reaction zone (2-8.
Among other benefits associated with the rapid vertical flow technique are the separation of sample and conjugate, which is conducive to better performance, and the "hook effect": in lateral flow, undiluted specimen will overwhelm the internal color conjugate upon reaction, prior to moving toward the reaction zone.
Frangible sealed reservoirs use differential weld strengths that are designed to fail under specific pressures, allowing for a unit-of-use measure to be precisely delivered to a target well or reaction zone.
The width of chemical reaction zone determines the critical detonation diameter [5].
To ensure a dilution of the reaction zone, a portion of the flue gases is mechanically driven within cylindrical conducts into the furnace entrance.
For several tens of seconds, a wide reaction zone was observed to move from the vicinity of the short circuit toward the end of the battery.
Such a relatively low hydrogen content was due to the extremely fast cooling rate of the products at the outlet of the reaction zone, about [10.
