Formation of Soot in High-Pressure Diffusion Flames
Abstract
Diesel engines continue to be the primary powerplant for the Army, both for propulsion and power generation. These engines operate at high pressures to maximize thermodynamic efficiency. Pressure has a direct effect on the peak temperature, the thermal and species gradients, and the species diffusion coefficients, all of which in turn affect the formation of soot in these flames. However, high-pressure flames have received very limited attention, primarily due to the experimental difficulty in operating these flames. Measurements of flame-generated species (using both sampling and non-intrusive optical diagnostics) will be made to help illuminate the chemistry-fluid mechanics interaction and the role of transport at high pressures. The overall goal is to reduce soot emission from these diesel powered vehicles in an effort to minimize their thermal signature.
