论文摘要
数值研究了强制对流中旋转碳氢化合物液滴的蒸发的热量和质量转移。在旋转强制对流中,我们的数值结果与文献中获得的比较显示了定性和定量令人满意的协议。已经确定了液滴的风和旋转速度的最佳值。提出了以DGHEIM和REYNOLDS数字来表达蒸发率的新相关性。还实现了其他新的相关性,以DGHEIM,REYNOLDS,PRANDTL和SCHMIDT数字来表达蒸发率。这些相关性考虑到可变的环境中温度,可变的质量分数,可变空气速度和可变的液滴初始半径在旋转强制对流中的液滴蒸发。
Heat and mass transfers of the evaporation of rotating hydrocarbons liquid droplet of ternary components, in forced convection are studied numerically. Comparison between our numerical results and those obtained in the literature shows qualitative and quantitative satisfactory agreements, in rotatory forced convection. Optimal values of the wind and rotational velocities of the liquid droplet have been determined. New correlations expressing the evaporation rate in terms of Dgheim & Reynolds numbers are proposed. Other new correlations expressing the evaporation rate in terms of Dgheim, Reynolds, Prandtl and Schmidt numbers are realized. These correlations take into consideration the evaporation of the liquid droplet of ternary components in variable ambient medium temperatures, variable mass fractions, variable air velocities, and variable droplet initial radii, in rotatory forced convection.
