چکیده انگلیسی
Experiments have been performed to obtain the temperature field and Nusselt number for a methane/air slot flame impinging into a cylindrical surface. Mach-Zehnder interferometry was used to determine the temperature. The effects of operation conditions including Reynolds number, equivalence ratio, distance between the burner and impingement surface, and the surface diameter were investigated. Results show that by decreasing the diameter of impingement surface, maximum heat flux increases and the location of maximum heat flux moves from the stagnation point towards the wall jet region. Increasing the Reynolds number creates a considerable heat flux both in the stagnation and the wall jet region. Equivalence ratio is the most effective parameter on the maximum flame temperature. Reducing the distance between the burner and impingement surface increases the heat flux, but, if the impingement surface is located through the inner reaction zone of flame, the heat flux decreases around the stagnation region.
