Session Hj - Shocks, Combustion & Hypersonic Flows.
ORAL session, Tuesday, November 25
310, Moscone Center
The combusting flow around a droplet was investigated through a direct numerical simulation method. Calculation was based on the three-dimensional full Navier-Stokes equations coupled with a single step chemical reaction model. The droplet was liquid octane, and the composition of free stream gas was equal to that of air. The temperature of the droplet was assumed to be constant, and then we considered only a gas-phase combustion process. Calculations were carried out under some free stream conditions, velocity and temperature. From our results, we observed some characteristic behaviors about droplet combustion.
