We study self-propelled dynamics of a droplet due to a Marangoni effect and chemical reactions in a binary fluid with a dilute third component of chemical product which affects the interfacial energy of a droplet. The equation for the migration velocity of the center of mass of a droplet is derived in the limit of an infinitesimally thin interface. We found that there is a bifurcation from a motionless state to a propagating state of droplet by changing the strength of the Marangoni effect.
我们研究了由于 Marangoni 效应和化学反应在二元流体中自推进动力学的液滴，该化学反应在界面能量影响液滴的稀第三组分的化学产物。在界面薄的极限条件下，导出了液滴质心迁移速度的方程。我们发现，通过改变 Marangoni 效应的强度，液滴从静止状态到传播状态发生了分岔。
