	1	Analytical and numerical studies on a single-droplet evaporation and combustion under forced convection显示文摘Existing droplet evaporation/combustion models in computational flui dynamics(CFD) simulation of spray combustion are based on simplifie 1-D models. Both these models and recently developed 3-D models of singledropletcombustiondonotgivetheconditionsforthedifferent existing droplet combustion modes. In this paper, droplet evaporation and combustion are studied both analytically and numerically. In the analytical solution, a 2-D axisymmetric flow surrounding an evaporating and combusting droplet was considered. The governing equations were solved using an integral method, similar to the Karman–Pohlhausen method for solving boundary-layer flows with pressure gradient. The results give a local evaporation rate and flam radius in agreement with experimental results. In numerical simulation, 3-D combusting gas flows surrounding an ethanol droplet were studied. The prediction results show three modes of droplet combustion under different relative velocities, explaining the changeintheevaporationconstantwithanincreaseinrelative velocity observed in experiments. This implies that different droplet combustion models should be developed in simulating spray combustion. The predicted local evaporation rate and flam radius by numerical simulation are in agreement with the analytical solution in the range of azimuthal angles 0?< θ < 90?. The numerical results indicate that the drag force of an evaporating and combusting droplet is much smaller than that of a cold solid particle, and thus the currently used drag models should be	L.X.Zhou K.Li	2015	Acta Mechanica Sinica2015，31，4：	5
