运用最大熵原理和质量守恒定律导出的喷雾液滴尺寸分布函数,建立了生物柴油—柴油混合燃料的喷雾液滴尺寸分布模型,对柴油、生物柴油—柴油混合燃料进行了模拟计算,并与试验结果进行了对比分析。结果表明,随着生物柴油掺混比的增大,燃料黏度增大,喷雾锥角变小,索特平均直径增大,计算数据与试验数据吻合很好。
Based on the principle of maximum entropy and the law of mass conservation, the spray droplet size distribution function was used to establish the spray droplet size distribution model of biodiesel-diesel hybrid fuel. The diesel fuel, biodiesel-diesel hybrid fuel was simulated and compared with the experiment The results of a comparative analysis. The results show that with the increase of the blending ratio of biodiesel, the viscosity of fuel increases, the cone angle of spray decreases, and the average diameter of Sot increases. The calculation data agree well with the experimental data.
