Abstract EN
The achievement of precise measurements on the laminar diffusion flames plays a big role in the process of realizing a wide flames range.
Despite most of fuel is likely burnt in the turbulent combustion, there is still data requirement for the data on the velocities of the laminar burning as input to several models of the turbulent combustion.
And, in engines with an internal combustion, the first combustion is laminar, thus once more, there is a requirement for the velocity of the laminar burning.
The burning velocity of the laminar diffusion flame was measured at three nozzles at different angles (30º, 45º, and 60º) and different distances between the nozzles burners (H = 20, 30, and 40 mm) with and without the N2, and wide range of equivalence ratios (0.65 ≤ϕ≤ 1.5).
Schlieren photographs were captured to qualitatively assess the effect of angle of nozzles, distance, and N2 on the burning velocity of the diffusion flame.
Burning velocity depends on the stagnation surface of the flame front, which in turn relies on the vertical distance (H) between the burners.
Also, it was noticed that the increase in distance between the burners leads to a decrease in the velocity of the reactants since it is affected by the air The achievement of precise measurements on the laminar diffusion flames plays a big role in the process of realizing a wide flames range.
