中文摘要：

结合微尺度条件下液体乙醇的流动和燃烧特性,通过理论分析选择合理的模型来对液体乙醇的微尺度层流扩散燃烧进行数值模拟,然后采用数值模拟软件Fluent来分析液滴辐射传热与边界层滑移因素对数值模拟的影响,将数值模拟结果与测量值进行对比分析.研究结果表明：将液滴辐射传热和边界层滑移因素结合起来考虑能使数值模拟值与测量值更接近.

英文摘要：

By taking into consideration the flow and combustion characteristics of liquid ethanol in microscale flow,a reasonable simulation model is selected based on theoretical analysis for the numerical simulation of microscale laminar-flow diffusion cumbustion of liquid ethanol,and the effects of droplet radiation heat transfer and boundary slip on the simulation are analyzed with Fluent.The simulated results are then compared with the measured ones finding that the numerical simulation considering both the droplet radiation heat transfer and the boundary slip is more accurate.
