Soot Formation in Laminar Diffusion Flames
Laminar, sooting, coflow diffusion flames at atmospheric pressure have been studied experimentally and theoretically as a function of fuel dilution by inert nitrogen. The flames have been investigated with laser diagnostics. Laser extinction has been used to calibrate the experimental soot volume fractions and an improved gating method has been implemented in the laser-induced incandescence (LI...
متن کاملDetailed Chemistry Modeling of Laminar Diffusion Flames On Parallel Computers
We present a numerical simulation of an axisymmetric, laminar diiusion ame with nite rate chemistry on serial and distributed memory parallel computers. We use the total mass, momentum, energy, and species conservation equations with the compressible Navier-Stokes equations written in vorticity-velocity form. The computational algorithm for solving the resulting nonlinear coupled elliptic parti...
متن کاملEffects of oxygen enhancement and gravity on normal and inverse laminar jet diffusion flames
A fire on the Mir space station in 1997 threatened the spacecraft and its crew of six [1]. The fire involved an oxygen jet leaking from a lithium–perchlorate oxygen generator. The fire involved three factors not normally encountered in terrestrial fires: enhanced oxygen, inverse flames (in that the oxidizer is surrounded by fuel), and microgravity. The present work examines some effects of thes...
متن کاملEffects of Magnetic Fields on Diffusion Flames
Since the time of Faraday, several researchers have studied the effects of magnetic fields on flames. In his time, Faraday realized that the application of certain magnetic field configurations to a burning candle resulted an equatorial elongation of the combustion zone [1]. Recent researchers have confirmed what Faraday observed over a century earlier by showing that flames bent to escape magn...
متن کاملLaminar Smoke Points of Nonbuoyant Jet Diffusion Flames
The laminar smoke point properties of jet diffusion f lames-the luminous flame length, the residence time, and the fuel flow rate, at the onset of soot emission from the flames--have proven to be useful global measures of the soot properties of nonpremixed flames. These measures provide a means to rate several aspects of sooting properties: the relative tendency of various fuels to emit soot fr...
