简介：在液相的质传上的Marangoni传送对流和它的影响被调查。Marangoni传送对流用激光Schlieren技术被设想。有序的多角形的传送对流模式和随机的界面的骚乱被观察。质传率上的效果ofMarangoni传送对流被使放出学习从在掉落的电影的水溶液的乙醇。试验性的结果证明那Marangoni传送对流能加快表面更新并且在液相提高质传率。液体传质系数能被差不多3褶层提高。相应实验关联以质传改进因素被给。在考虑Marangonieffect，而且，常规质传关联被修改。关联和试验性的数据预言的价值之间的差别在±8.2%以内，平均差别是4.2%。

简介：自从喷气和爆炸，气体的产品被锋利的接口分开，传统的弄平的粒子水动力学(SPH)方法是困难的在接口避免计算不稳定性。多相的SPH(MSPH)方法被用于改进稳定性，哪个smoothes粒子密度并且在接口使压力连续。形成过程的喷气的数字例子被用来测试MSPH方法的能力。结果证明方法为在喷气和气体的产品之间的大密度坡度仍然是算法稳定性并且有潜在的申请到爆炸和喷气问题。塑造的费用的开始方法的效果也被讨论。
