1217409 PI: BalachandarVolcanic eruptions, powder snow avalanches, turbidity currents, dust storms and bubble plumes are diverse examples of environmental flows. But they share a lot of common physics. Fundamentally all these flows are environmental examples of dispersed two-phase turbulence. For example, both in turbidity currents and powder snow avalanches the key common physics is in accurately capturing the competition between deposition and resuspension from the bottom boundary. Similarly, entrainment of ambient fluid is the process that plays a key role in the vertical development of volcanic and bubbly plumes. Despite these commonalities, the progress of mathematical models, closures and simulation techniques have gone on independently. Especially, the recent rapid expansion of research enterprise has greatly diminished the potential for cross fertilization of ideas. The purpose of the workshop is to bring world-class experts from these different disciplines and promote cross fertilization of ideas and methodologies. The workshop is held at the University of Florida, Gainesville, FL, from March 14th to March 16th of 2012.The intellectual merit of the workshop is to identify key outstanding challenges that are common and thereby enable better understanding, modeling and predictive simulations of a broad class of complex environmental turbulent multiphase flow problems. The broader impact of the workshop will be through wide dissemination of the workshop results and findings through a dedicated website and also by publishing the key contributions as a state of the art book.

1217409 PI：Balachandarvolcanic爆发，粉末雪雪崩，浊流，防尘暴风雨和气泡羽流是环境流的各种例子。但是他们有很多常见的物理学。从根本上讲，所有这些流都是分散两相湍流的环境例子。例如，在浊流和粉末雪雪崩中，关键的常见物理是准确捕获底部边界的沉积和重悬的竞争。同样，环境流体的夹带是在火山和起泡羽流的垂直发展中起关键作用的过程。尽管有这些共同点，但数学模型，封闭和仿真技术的进展还是独立进行的。尤其是，最近的研究企业的快速扩张大大削弱了思想交叉施肥的潜力。研讨会的目的是从这些不同学科中带来世界一流的专家，并促进思想和方法的交叉施肥。该研讨会于2012年3月14日至3月16日在佛罗里达州盖恩斯维尔的佛罗里达大学举行。研讨会的知识分子是确定普遍的关键杰出挑战，从而使人们可以更好地理解，建模和预测性模拟，以了解一系列复杂的环境湍流流动问题。研讨会的更广泛影响将是通过专门的网站广泛传播研讨会的结果和调查结果，并通过将关键贡献作为最先进的书籍发表。
