A new computational procedure for simulating liquid jets in crossflows with atomization is described and demonstrated. In our previous work, the integral form of the conservation equations has been used to derive explicit quadratic formulas for drop size during spray atomization in various geometries. This formula relates the drop size with the local kinetic energy state, i.e., the velocities, so that local velocity data from liquid-phase simulation prior to atomization can be used to determine the initial drop size. This initial drop size and appropriately sampled local gas velocities are used as the initial conditions in the dispersed-phase simulation. This procedure has been performed with good validation and comparison with experimental data at realistic Reynolds and Weber number conditions. This approach is based on the conservation principles and is generalizable so that it can easily be implemented in any spray geometries for accurate and efficient computations of spray flows.

雾化横流中液体射流的计算协议

描述和演示了一种新的计算过程，该过程模拟了带有雾化的横流中的液体射流。在我们之前的工作中，守恒方程的积分形式已被用于导出各种几何形状的喷雾雾化过程中液滴尺寸的显式二次公式。该公式将液滴的大小与局部动能状态（即速度）相关联，以便可以使用雾化之前液相模拟得到的局部速度数据来确定初始液滴的大小。该初始液滴尺寸和适当采样的局部气体速度用作分散相模拟中的初始条件。在现实的雷诺兹和韦伯数条件下，已对该程序进行了良好的验证并与实验数据进行了比较。
