Sentence examples for flames decreased from inspiring English sources

The results showed that the extinction strain rate of n-decane/toluene/nitrogen flames decreased significantly with an increase of toluene addition and depended linearly on the maximum OH concentration.

The stand-off distance above the flame holder for those flames decreased and heat transfer from the flame base to the flame holder became more intense when the mixture velocity was increased.

The maximum centerline soot volume fraction in the flames decreased strongly and monotonically as air was added to the fuel, with a reduction of one half from the non-premixed flame to a flame with a primary equivalence ratio of 15.

The current study reveals that the radiative heat release factor of syngas flames decreases at higher firing inputs.

The new reduced-chemistry descriptions can be useful for both analytical and computational studies of lean hydrogen air flames, decreasing required computation times.

Two main discrepancies are revealed: firstly, the apparent liftoff height of n-heptane flames decreases gradually with the increasing coflow oxygen level, while the apparent liftoff height of other fuels exhibit a non-monotonic trend; secondly, a transitional flame structure of n-heptane occurs in a coflow with XO2 = 3%, while this structure occurs in a coflow with XO2≥ 9% for other fuels.

The thickness of the flame decreased with decreasing oxygen concentration.

The flame height, marked by visible flame radiation, remained constant at about 5.5 mm and the cross-sectional area of the flame decreased with increasing pressure.

The calculated temperature along the trailing flame decreased downstream due to radiative cooling, leading to local extinction at <1300 K and flame tip opening.

Under the microgravity condition, the results showed that the propagation speed of tribrachial flame decreased with the mixture fraction gradient, in agreement with previous studies.

The experimental results show that under certain conditions the application of the magnetic field decreased the flame height, prevented the flame from attaching to the prisms, increased the intensity of the flame, decreased the flow rate for which visible soot inception occurred, and increased the flow rate below which the flame extinguished.
