Andreas AcrivosCTS - 0613149CUNY City CollegeThe flow of multiphase materials, such as suspensions of solid particles, drops & bubbles inliquids, is encountered frequently in a variety of industrial processes as well as in nature, hencethe subject has received a considerable degree of attention from both the fundamental & practicalpoints of view. Yet, compared to the more traditional area of single-phase fluid mechanics, theresearch activity in multiphase fluid dynamics has not been on a scale commensurate with theimportance and complexity of the field. For example, although it is well known that the dynamicsof single -phase materials can be accurately described by means of the Navier-Stokes equations,which at present can be solved using a variety of analytical or numerical techniques, acorresponding set of fundamental equations for multiphase materials is currently unavailableexcept for special cases. Similarly, there is a dearth of experimental methods able to capture thedetailed structure of multiphase flows compared to those currently available for their single-phasecounterparts. It the purpose of this Symposium to try and remedy this situation by bringingtogether some of the key researchers in a subset of this broad field and, through active discussions& interchange of ideas, lay the foundations for organizing a concerted effort to attack some of themajor issues which need to be resolved.The Symposium is entitled "Recent Advances in Multiphase Flows: Numerical & Experimental"and will take place 11 14 June 2007, in Istanbul, Turkey. The meeting is under the auspices ofthe International Union on Theoretical & Applied Mechanics (IUTAM) and is co-sponsoredby the Istanbul Technical University. IUTAM, in existence for the better part of a century, is awell-known international organization. It organizes the IUTAM Congresses every 4 years andsponsors about a dozen or so Symposia every year all dedicated to the advancement ofmechanics. This particular Symposium is organized by the Principal Investigator, together withProfessor Can Delale (Istanbul Technical University), plus a 6 member international scientificcommittee. This proposal seeks partial support from the National Science Foundation in order tofacilitate the attendance of several American students and other researchers who would otherwisenot be able to attend.The meeting will bring together a small but select group of researchers active in the fundamentalsof multiphase fluid dynamics especially as concerns the development of: (a) fundamental basicequations for describing such systems; (b) general purpose numerical techniques for solving suchequations; and (c) novel experimental methods for measuring the detailed structure of such flowsand thereby testing the model predictions. Potential applications include micro- and nanosystemsinvolving particulate and other multiphase flows, suspension flows, mixing, drop break-up &coalescence, combustion, electric and magnetic field driven phenomena, etc.The number of attendees will be capped at 70-75 to maintain a workshop atmosphere wherefuture research directions in the subject field will be identified for the benefit of the community ingeneral and the National Science Foundation in particular. There will be no parallel sessions, butthere will be plenty of opportunities for fruitful discussions. The intellectual merit of theproposed activity lies in bringing together 3 communities in this field who seldom interact withone another, viz. those involved with: (a) developing rational fundamental equations for modelingmultiphase flows; (b) those developing simulation techniques for solving these equations; and (c)those developing novel experimental tools for testing in detail the theoretical predictions.

多相材料的流动，如固体颗粒的悬浮液，液体中的滴泡，在各种工业过程中以及在自然界中经常遇到，因此，从基本的实践观点来看，这个问题已经得到了相当程度的关注。然而，与更传统的单相流体力学领域相比，多相流体动力学的研究活动还没有达到与该领域的重要性和复杂性相称的规模。例如，尽管众所周知，单相材料的动力学可以用纳维-斯托克斯方程精确地描述，目前可以用各种分析或数值技术来求解，但除了特殊情况外，目前还没有一套相应的多相材料基本方程。同样，与目前可用于单相流的实验方法相比，缺乏能够捕获多相流的详细结构的实验方法。这是本次研讨会的目的，尝试和补救这种情况bringingtogether一些关键的研究人员在这个广泛的领域的一个子集，并通过积极的讨论交流的想法，奠定了基础，为组织一个协调一致的努力，攻击一些themmajor问题，需要解决。研讨会的标题是“最近的进展多相流：数值实验“，并将于2007年6月11日至14日，在伊斯坦布尔，土耳其。会议由国际理论应用力学联合会（IUTAM）主办，伊斯坦布尔技术大学协办。国际旅游业协会是一个著名的国际组织，已经存在了大半个世纪。它每4年组织一次IUTAM大会，每年赞助大约12次研讨会，所有这些研讨会都致力于力学的进步。这个特殊的研讨会是由首席研究员，连同教授可以Delale（伊斯坦布尔技术大学），加上一个6名成员的国际科学委员会。这项建议寻求国家科学基金会的部分支持，以方便一些美国学生和其他研究人员参加会议，否则他们将无法参加。会议将汇集一个小的，但选择的研究人员小组，积极在多相流体动力学的基础，特别是有关的发展：（a）基本的基本方程，用于描述这种系统;（B）求解这类方程的通用数值技术;（c）测量这类流动的详细结构并由此检验模型预测的新的实验方法。潜在的应用包括涉及微粒和其他多相流，悬浮液流，混合，液滴破裂聚结，燃烧，电场和磁场驱动的现象等微和纳米系统。与会者的人数将在70-75保持研讨会的气氛，其中在该主题领域的未来研究方向将被确定为社会的整体利益，特别是国家科学基金会。不会有平行会议，但会有很多机会进行富有成果的讨论。拟议活动的智力价值在于将该领域中很少相互作用的三个群体聚集在一起，即：（a）开发用于模拟多相流的合理基本方程的群体;（B）开发用于求解这些方程的模拟技术的群体;以及（c）开发用于详细测试理论预测的新颖实验工具的群体。
