Film Flow Instabilities & Spatiotemporal Dynamics

研究，主要是实验，将集中于在固体表面上流动的薄液膜发生的各种不稳定现象。孤立波之间的非线性相互作用，三维波型，以及时空无序的增长将被研究。薄膜厚度观测将用于测试用于表示和分析空间和时间复杂数据的各种当前方法和理论。薄膜流动不稳定性在各种技术中都具有内在的意义。此外，胶片是检验涉及无序和噪声的新兴思想的极好试验场，也是从无序系统中提取有意义信息的有用诊断方法。因此，这种方法不仅适用于薄膜，而且适用范围更广。*//

Research, primarily experimental, will be focused on the various instability phenomena which occur for thin liquid films flowing over a solid surface. Non-linear interaction between solitary waves, three-dimensional wave patterns, and the growth of spatial and temporal disorder will be investigated. Film thickness observations will be used to test various current methods and theories for the representation and analysis of spatially and temporally complex data. Film flow instabilities are of intrinsic interest in a variety of technologies. In addition, films are an excellent testing ground of emerging ideas involving disorder and noise, and useful diagnostics to extract meaningful information from disordered systems. Thus the applicability is wider than only to thin films. ***//
