周期性强迫表面波中双临界点附近的菱形斑图

Rhombic Patterns Near a Bicritical Point in Periodically Forced Surface Waves

Krishna Kumar, Supriyo Paul, Dharmesh Jain

摘要:

我们在这里提出了一个研究的菱形模式选择接近双临界点在粘性流体的主表面不稳定性的发病下,两个频率的垂直振动。菱形图案似乎是自然的,在主不稳定性的形式,一个双临界点,如果驱动频率的比例选择适当。我们提出了两种不同的模式,这可能是在法拉第实验。

英文摘要:

We present here a study of selection of rhombic patterns close to a bicritical point at the onset of primary surface instability in viscous fluids under two-frequency vertical vibration. Rhombic patterns appear to be natural at the primary instability in the form of a bicritical point if the ratio of driving frequencies is selected properly. We present two different patterns which may be accessible in a Faraday experiment.
