Experimental Investigation of Thermal characterization of Impinging two Flame Jets with landfill Gas

In this study, the thermal characteristics of two impinging flame jets are investigated. For the flame structure and temperature field analysis, a non-contact method named Mach-Zehnder Interferometry is used. Mach zehnder method is utilized to determine the effective parameters of flame structure in different amount of Reynolds number and equivalence ratio. The hydraulic diameter of the burners is considered 1.3 mm with 20 mm length and 10 mm width. The angle between two burners is 77 degree. The effect of fuel/air ratio is investigated, when Reynolds number is 70 and equivalence ratio varies between 0.8 and 2.5. Maximum temperature and velocity occurs in equivalence ratio of 1 but at this point, increasing of Reynolds number leads to enhance the maximum temperature and at the same time the growth of the maximum temperature domain.
