  4. Abstract:
  5. In this work, we numerically study the effect of a mini-scale primary-air injector on the formation of soot nano-particles in a model tubular-type gas-turbine combustor fed with JP, i.e. gaseous JP-1. We solve a documented experimental (benchmark) test case to evaluate our numerical solution and compare the achieved flame structure with that of the measured and reported data. The obtained numerical results show good agreements with the experimental data. After ensuring the validity of numerical tool, we install a mini-scale injector, split the incoming air-flow between the primary and secondary streams, inject the primary air into the combustor via the mini-scale injector, and compare the achieved results with those of the original benchmark test case. Our results show that the injected-primary-air flow effectively reduces the emission of soot nano-aerosol in the exhaust gases
