Heat transfer and wall pressure characteristics of a twin premixed butane/air flame jets

Heat transfer characteristics of an array of impinging pre-mixed slot flame jets

“…The between-jet interference occurred at different jetto-jet spacings as observed from the flame appearance could be supplemented by the variation of the local pressure on the impingement surface, which was obtained in the AuthorsÕ previous work [31]. Conclusively, it can be assumed that the chance to obtain a diffusion flame at the present equivalence ratio (/ = 1) is quite negligible.…”

“…The optimal jet-to-jet spacing corresponding to the highest area-averaged heat flux for the jet array under consideration was observed to be 2.5 at Re = 1000, / = 1 and H/d e = 2. According to the AuthorsÕ previous studies [26,27,30,31], thermal characteristics of impinging jet varies with Reynolds number, equivalence ratio and nozzle-to-plate distance rather significantly. It is therefore very reasonable to expect that the optimal jet-tojet spacing would be varied with Re, / and H/d e .…”

Emission of impinging swirling and non-swirling inverse diffusion flames

“…The heat transfer behaviors of a slot impinging premixed flame have been investigated by Dong et al [8]. They also extended their investigations to an array of two and three impinging premixed flames [9,10]. Huang et al [11] examined the heat transfer characteristics of an impinging premixed flame with induced swirl.…”

Heat transfer characteristics of three interacting methane/air flame jets impinging on a flat surface

“…Dong et al [15][16][17][18] studied the heat transfer characteristics of three inline laminar flame jets forming a subset of an inline array of flame jets. They inferred from their experiments that a positive pressure was produced at the jet interaction zone where two adjacent jets met and collided with each other.…”
