摘　　要：建立了描述水平热壁上方油料着火过程的模型,选择合适的着火判据,按照泄漏油料着火实验的相应条件进行数值计算.根据计算结果分析了热壁上泄漏油料运动过程及着火方式.将计算结果与实验结果进行比较,分析了热壁沸腾传热对着火延迟和着火高度的影响.To describe the ignition process of fuel vapor on a horizontal surface a three dimensional model was built. The appropriate ignition criterion was chosen for numerical calculation. The results were compared with the experimental counterparts. The fuel vapor movement and ignition were studied based on the numerical results. At the same time, the key factor in ignition delay and ignition height was given.
