Abstract

There is general interest in understanding sooting behavior in canonical flames at elevated pressures. In this study, a new apparatus is used to evaluate sooting turbulent non-premixed flames at 1 atm and 3 atm, with constant Reynolds number. Laser-induced incandescence is used to assess the distribution and amount of soot in both flames. The results show that increasing the pressure has the effect of creating larger and more intense instantaneous regions of soot, reducing the length of the non-sooting region immediately downstream of the nozzle, and increasing the amount of soot by more than an order of magnitude.
