• Unsteady combustion and gasification of a fuel droplet in high-temperature flowsare studied numerically. In the course of droplet burning, particle deceleration and a moving grid system are included to account for the impacts of drag force and droplet regression. The simulated results show that the convective droplet is ignited with a wake flame after a heating-up period. With increasing time the relative velocity between the droplet and surrounding flow becomes smaller due to the drag. As a result, the flame changes from a wake type, through a transition type, eventually to an envelope one. The vaporization fluxes predicted in terms of various quasi-steady models are also compared with the present solution. The quasi-steady analysis, omitting the initial droplet heat-up process, fails in predicting the flame configurations and vaporization flux in the initial period of the droplet lifetime. When the envelope flame develops around the droplet, the predictions by the quasi-steady models are in good agreement with the transient solution, except the vaporization model. Furthermore, if the droplet undergoes a sudden drop in ambient temperature, it reveals that the dual solution of the quasi-steady model enable us to predict the droplet vaporization rate and flame configuration well.
