## The simulation results indicated: 1) by increasing of We number, the dynamic behaviors of droplets were changed from coalescence to flexible separation with the formation of satellite droplet; 2) with the increasing of Oh number, the degree of deformation of the droplet collisions became smaller; 3) the larger the gas viscosity was, the greater the resistance that the droplet movement would be; 4) the change of dynamic behaviors of droplet collisions when varying DR from 135 to 750 was negligible if other parameters and conditions were maintained the same; 5) for the off-center collisions with the same Oh number, increasing We number led to the formation of a long and thin "ligament" in between the droplets, which was finally separated into two satellite droplets. シミュレーション結果は次のことを示した。1）We数を増やすことにより、液滴の動的挙動が合体から衛星液滴の形成を伴う柔軟な分離に変化した。 2）Oh数の増加に伴い、液滴衝突の変形の程度は小さくなりました。 3）ガスの粘度が高いほど、液滴の動きに対する抵抗が大きくなります。 4）他のパラメータと条件が同じに維持されている場合、DRを135から750に変化させたときの液滴衝突の動的挙動の変化は無視できました。 5）同じOh数の中心から外れた衝突の場合、We数を増やすと、液滴間に長くて薄い「靭帯」が形成され、最終的に2つの衛星液滴に分離されました。
