Research Abstract

To investigate the effect of jet-to-jet spacing of multiple impinging oxidizer jets on burning rate of solid combustibles, experiments with different jet-to-jet spacing nozzles were performed. Main achievements are as follows.
1. Lateral profiles of burning rate using double impinging oxidizer jets were entirely different depending on spacing of the nozzle. Typically, the point at which maximum burning rate was obtained was shifted outside for the wider spacing nozzle.
2. The Dependence of burning rate on Reynolds number was also shown. As well as heat transfer dependence in the stagnation region of non-combustion case, the burning rate was proportional to Reynolds number to the power of 0.5. On the other hand, the burning rate just below the slits for the case of wider jet-to-jet spacing was proportional to Reynolds number to the power of 0.8.
