Abstract

We investigate the use of an experimental temperature profile to generate solutions for a sooting, coflow laminar diffusion flame with detailed transport and finite rate chemistry. Experimentally, four diagnostic techniques are used to measure the two-dimensional temperature field in an ethylene-air coflow flame. The experimental temperature profile is used to constrain the solution of the energy equation, thus obviating the need to model radiative losses in the flame. Results are presented for a 40% ethylene-air coflow flame.
