摘要: Abstract In this chapter, we consider the motion of a droplet and surrounding flow accompanied by motion. Our specific attention is on spontaneous autonomous droplet. Such system has no applied external force asymmetry imposed priori. Nevertheless, moves consuming energy breaking symmetry system. The phenomenon reminds us biological systems that can also move spontaneously. These systems, which are called self-propulsive have recently been extensively studied after several model experiments were proposed using chemical reactions. mechanism such less clear, though theoretical computational studies revealed novel aspects in contrast with under given asymmetry. We discuss developed experimental systems. Then, focus suspended swims, explain how result be analyzed terms hydrodynamics concept surface tension. Finally, apply method to analysis swimming induced propelled pattern generated inside
