Correlation of Projected Flame Height for Impinging Horizontal Jet Flames

Horizontal jet flame is said to be among the most dangerous types of fire considering a possible impingement effect on nearby facilities. Numerous studies have been conducted and assessed for geometrical flame features of jet flames as it imposed dangers where nearby equipment is included. However, data on flame height are often missing considering the effects may be deteriorative in the presence of nearby equipment. This study was carried out by using propane as fuel and the jet fire was released from a circular nozzle (diameter of 7.15 mm and 9.8 mm). The purpose is to determine a suitable correlation to be used to predict the flame extension length in the case of an impingement scenario. A review of the literature revealed that existing correlations are inapplicable to impinging jet fires. This study offers a better correlation which used elliptical flame shape assumption as a basis. A new correlation was suggested based on the experimental condition which is ?? ?? ?? ~31.4 1 9 ?? ??-???????? 3 - 1 3 ?? 3 ???? ?? ??-???????? ?? + 1 9 ?? 3 ?? 1 9 ?? ??-?????? 3 ???? 1/2 .
