Laminar Burning Speed

A numerical study has been carried out to investigate the impact of adding syngas into JP-8 fuel. A new chemical mechanism has been assembled from existing mechanism of JP-8 and syngas and has been examined by comparing with the experimental data from literatures. The mechanism was then applied to Cantera zero-dimension constant internal energy and constant volume model and one-dimensional (1D) freely propagating flame model to calculate the ignition delay time and laminar burning speed, respectively. The simulations were carried out over a large range of temperature (700–1000 K), blending ratio (0–20% syngas), and H2/CO ratio (10/90 to 50/50). Simulation results showed that the blending syngas with JP-8 will slightly increase the ignition delay time and laminar burning speed.

Dust Dispersion

Numerical simulation was used to obtain the transient concentration of dust in the process of dispersion in a closed vessel in this work. Through the transient concentration of dust obtained by numerical results, the best ignition delay time can be evaluated. For the 5 L vessel and the hemispherical injection nozzle and under the blow pressure of 0.5 MPa, the ignition delay time should be 50-100 ms. Numerical results agree with the data obtained in the experiments under the same condition. It is difficult that dust concentration in the process of dispersion reaches absolutely uniform everywhere in the closed vessel.
