A third annular weakly swirling airflow provided the flame stabilisation mechanism.
With a freely expanding self-accelerating spherical flame as an example, it is shown that deflagration-to-detonation transition in unconfined gaseous systems is indeed possible provided the flame is large enough.
With a freely expanding unwrinkled spherical flame as an example, it is shown that deflagration-to-detonation transition in unconfined gaseous systems is possible, provided the flame is close to its propagability threshold and the deficient reactant Lewis number is not too small.
At a place like Midwood, which draws on a less elite population than city schools with admission exams, like the traditional powerhouses Stuyvesant and the Bronx High School of Science, the Intel contest provides the flame that heats a new, high-tech version of the melting pot myth.
If you do chose to use a real candle, make sure your carving will provide the flame with enough oxygen to keep burning.
For a fixed swirl number, it is found that N2- and CO2-diluted CH4/O2 flames at the same equivalence ratio feature very similar shapes provided the adiabatic flame temperature and the ratio of bulk velocity to laminar burning velocity are kept the same although the absolute value of bulk velocity and the general velocity level inside the combustor are different.
Newfangled gas stoves and fireplaces can provide the hypnotic flames and the radiating heat without the labor (though also without the crackle -- until someone comes up with a speaker attachment).
Music in Middletown Walt Whitman's famous Civil War poem, "By The Bivouac's Fitful Flame," provided the inspiration for a work to be performed at 2 p.m. today by the New World Consort and Peter Standaart, flutist.
In general, the formulations containing only ATH couldn't provide the effective flame resistivity as compared to that of the APP-filled composites.
This study indicates that CO2-diluted CH4/O2 premixed swirling flames can be stabilized with similar shapes as CH4/air flames without design modification provided the suggested similarity is obeyed.
