abstract: Enhanced mixing and transport properties are distinguishing characteristics of both turbulent and more structured complex flows. The concepts of eddy diffusion and eddy viscosity, for example, were introduced as attempts to 'parameterize' these effects to produce reduced models for theoretical analysis and simulations. At the same time turbulent mixing and transport is the focus of significant attention from a fundamental point of view, based in some cases on the Navier-Stokes equations and in other cases on models or special flows amenable to more thorough analytical investigations. This workshop is concerned with modern mathematical approaches to the study of transport and mixing in turbulence and other complex flows, including transitional flows with significant attention to applications from the applied sciences, predominantly geophysics.

abstract: The First International Conference on Self-Organization in desiccated drops of multi-component fluids: experiments, theories, applications is organized to provide an interface for researchers from diverse scientific disciplines but with common interests in nonlinear dynamics and complex systems. This meeting will draw together researchers to share their most recent results in understanding, modeling, and controlling nonlinear dynamical systems. The meeting is addressed to Mathematicians and Physicists, Engineers and medical people.

abstract: Over the last several years, there have been major advances in the experimental observation and theoretical understanding of turbulent plasmas and fluids. This meeting will bring together theoreticians and experimentalists from three different fields, namely plasma turbulence, fluid turbulence, and dynamo physics. Some of the overarching themes will be pattern formation, coherent structures, and the dynamics of tracers in turbulent flows. The goal is to review our current understanding of turbulent plasmas and fluids, to exchange ideas between these research areas, as well as to foster collaborations.

abstract: The Mathematics Department at the University of Texas – Pan American will host an NSF/CBMS regional research conference on Nonlinear Water Waves with Applications to Wave-Current Interactions and Tsunamis during the week of May 17-21, 2010.

Varvaruca, and possibly others. Participation is open to scientists working at research level on theoretical and practical aspects of the conference’s topic. Some limited support is available for travel and local expenses. Underrepresented groups are strongly encouraged to apply.

abstract: Natural locomotion in fluids includes the swimming of fish and microorganisms and the flying of birds and insects. Other creatures employ similar movements on solid and fluid surfaces, e.g., snails, snakes, and water striders. Nature has exploited the complex fluid dynamics of time-dependent three-dimensional flows over a wide range of Reynolds numbers to evolve a variety of interesting mechanisms of locomotion. This workshop will focus on the mechanics of these behaviors and the current state of theoretical and experimental work in the field. The scope will cover the dynamics from low to high Reynolds numbers, emphasizing the links between the fluid dynamics and the nature of the evolved mechanisms. The inclusion of movement over solid and fluid surfaces introduces new phenomena involving surface stresses and complex fluid layers.

abstract: The interplay between biological organisms and hydrodynamic flows influences strongly the ecology of oceans, lakes and rivers, as well as developmental processes in living organisms. These phenomena at the interface between biology and physics cover different temporal and spatial scales from small-scale turbulence to mesoscale hydrodynamic activity on the physical side, and from bacteria and other cellular organisms up to swimming animals like fish on the biological side.

The aim of this workshop is to bring together scientists from various disciplines who investigate organisms in fluid flows from different perspectives and to address, among others, topics like: impact of mesoscale mixing on biology, population dynamics in rivers, non-passive transport, experimental biology in fluids, bioconvection and the influence of small-scale turbulence on plankton. The general goal of the workshop is to facilitate cross-fertilization between the different scientific communities and to stimulate joint interdisciplinary projects among the participants.

abstract: The goal of the Liblice meetings held every fourth year is to provide an effective forum for contacts and for the exchange of ideas, with emphasis on discussions rather than on formal presentations. The meetings are intended to give a clear picture of the achievements and challenges in both theoretical and applied aspects of the discipline.

abstract: The conference will focus on research in mathematical fluid dynamics, spanning areas from rigorous analysis of nonlinear partial differential equations to numerical analysis and modeling of related physical systems. This includes: (1) Analysis of PDEs for fluid dynamics: rigorous results for regularity, existence, uniqueness for Navier-Stokes and Euler, problems with free-surfaces and surface tension, convergence of vortex methods and splitting methods, (2) Fluid motion driven by interfaces: computational methods and analysis of problems with moving interfaces and (3) Computational methods for fluid dynamics. Thomas Beale has made important contributions to many problems in these areas.The conference will feature talks by a list of invited speakers and an extended poster session for contributed research presentations by conference participants.

abstract: There is tremendous interest in the development and application of advanced computational techniques for simulating the motion of an incompressible fluid driven by flexible immersed structures, in large part owing to the multitude of applications in physiology and biology. Active biological tissue is typically constructed of fibers that are surrounded by fluid; the fibers not only hold the tissue together but also transmit forces that ultimately result in fluid motion. In other cases, the fluid may flow through flexible conduits such as a blood vessels or airways that both react to and affect the fluid dynamics. Additional examples arise in the context of external fluid flows in biological and engineering applications, such as dynamics of insect wings, flagellated or ciliated organisms, suspensions of blood cells and other synthetic particles, parachute dynamics, and so on. The workshop will include two tutorials targeted to graduate students and junior mathematicians, with the goal of providing training opportunities to young scientists. The meeting will be organized around three main themes: Formulation and analysis of the underlying governing equations. Algorithmic and computational issues related to increasing accuracy and efficiency through use of adaptivity, novel time-stepping schemes and parallelism. Applications to problems in the biological, physical and engineering sciences. Selected papers will be published in a special issue of Communications in Computational Physics after the workshop.

abstract: Dynamics Days Europe is a major annual international conference aimed at bringing together theoretical and experimental scientists from a variety of disciplines, including nonlinear dynamics, theoretical physics, fluid dynamics and mathematics.

abstract: Fluctuation-induced and effective forces play an important role in controlling the structure, the dynamics, and the phase behavior of soft and condensed matter, ranging from colloidal suspensions to liquid crystals, complex fluids, and wetting films. These forces typically act at the sub-micrometer scale and arise from spatially confining various media in which there are pronounced quantum or thermal fluctuations. Recent theoretical and experimental investigations demonstrate that such forces can provide versatile tools for controlling and manipulating the behavior of systems at small scales. The workshop will promote an active and lively discussion of recent theoretical and experimental advances in understanding the various manifestations of effective and fluctuation-induced forces, with particular emphasis on unifying concepts and possible technological and interdisciplinary applications. Formulating perspectives for future developments will be strongly encouraged.
