| Abstract: | The particle stochastic trajectory model which accounts for random fluctuations both
in magnitude and direction of the instantaneous gas velocity is utilized in the present paper. The
particle motion under the interactions between the swirling and non-swirling jets in a swirl combustor
is numerically simulated. The distributions of particle total axial mass flux and axial and tangential
velocities are obtained. They agree with the measured data and are improved over the results obtained
by using Gosman's particle stochastic trajectory model. |
