Spiral structures from heavy particles at parametrical excitement of standing capillary waves

The paper presents experimental studies on the formation of spiral structures of heavy particles by the field of parametrically excited standing spiral waves. Particles move under the influence of the average currents field generated near the bottom in a viscous liquid by standing waves. The formation of structures has a threshold character and depends on the intensity of the field of standing waves. Formation of multi-armed structures revealed.
