在理想羽流模型和Raj羽流倾角模型的基础上,对水平风作用下的空间非受限羽流的质量流率进行了几何简化分析,获得了水平风作用下空间非受限羽流质量流率的计算方法.并以两种功率的甲醇火为研究对象,对水平风下的羽流烟气生成量进行了示例计算.结果表明,在1～2 m/s水平气流的影响下,烟气生成量较无风条件下轴对称羽流质量流率增加了1～2倍.

Based on ideal plume model and Raj's model of tilted plume affected by wind, study on mass flow rate of plume under horizontal wind was performed. Method for predicting mass flow rate of tilted plume was proposed. Calculation of smoke generation of two pool fires with methanol as fuel under different velocities of horizontal wind were carried out and the results showed that under horizontal wind of 1 m/s～2 m/s,mass flow rate of tilted plume might be increased by 100% to 200%.
