“…Research work on pool fire in a quiescent atmosphere was done which targeted on the burning rate, the flame height and pulsation, the thermal radiation, the total kinetic energy, and the burnt gas emission [6][7][8]. Moreover, research work on pool fire that affected by cross airflow has been done [9][10][11][12][13][14][15][16][17]. Gasoline pool fire under cross airflow was studied [10] and found that the mass burning rate of gasoline at certain cross air velocity decreased with pool size and vice versa with quiescent air condition.…”

“…Moreover, they found that heat transfer by radiation was nearly negligible at higher velocity of cross airflow. Tao et al [17] studied the flame length of alcohol and n-heptane pool fire under cross airflow and found that the flame length increased with airflow velocity. The flame length influenced heat release rate directly and significantly influenced the combustion efficiency.…”

Burning rates of the biodiesel B7 and blended with 10 %vol. and 15 %vol ethanol in 50 mm diameter of pan were investigated. Angle of the pan wall was set to 0 deg. and 60 deg. and 1 m/s to 3.5 m/s of longitudinal air, flows across the pan. Results show that, as increase in the longitudinal airflow speed, the burning rates of biodiesel B7+15 %vol ethanol increased, but it decreased for the biodiesel B7 and biodiesel B7+10 %vol. ethanol. Moreover, burning rate of 0 deg. is higher than that 60 deg. for all cases. It is concluded that for the case of biodiesel B7+15 %vol ethanol, incoming air helps in increasing the burning rate. But for biodiesel B7 and biodiesel B7+10 %vol. ethanol, the incoming air reduces the pan temperature and leads to low burning rate. Furthermore, 0 deg. case gives a higher burning rate for all fuels because flame tilt significantly and increased the rate of heat transfer by conduction and radiation from the flame to the fuel. The 60 deg. case showed that flame is less tilted thus leads to less burning rate.
