Sentence examples for flame front progressing from inspiring English sources

In a properly functioning engine, the charge burns with the flame front progressing smoothly from the point of ignition across the combustion chamber.

With the planar conditioned particle image velocimetry (CPIV) technique, simultaneous access is given to the flow, turbulence, and flame position data, using PIV for flow and turbulence and the density jump at the instantaneous flame front for reaction progress variable and density.

In the conditional statistics approach, the instantaneous centerline profiles of OH mass fraction and its gradient are used to identify (i) the interface between the two counterflowing streams referred to as the gas mixing layer interface (GMLI), and (ii) the turbulent flame front using a binary reaction progress variable, c.

The coupling with the G-equation ensures that the flame front described by the filtered reaction progress variable moves with the correct propagation velocity, independent of numerical diffusion caused by an underresolution of the flame.

To have a good estimation of the NO mass fraction produced in the flame front and in the burnt gases, two progress variables are used.

Flame front propagation was monitored with thermocouples.

However, the mean widening for progress variable contours of premixed turbulent flames in comparison with corresponding values of unstrained premixed laminar flames was insignificant, implying that the influence of turbulent eddies on the flame front broadening is negligible.

This combustion zone is usually called the flame front.

Both flame front reaction and post-flame processes contribute to the heat release rate.

The flame front structures varied significantly with Reynolds number from wrinkled flame fronts to fragmented and strongly corrugated flame fronts.

Significant fluctuation of the XPS flame front is observed while the movement of the pyrolysis front is relatively stable.
