Newswise — The 64th Annual Meeting of the American Physical Society's (APS) Division of Fluid Dynamics (DFD) will include more than 2,000 compelling presentations from across the physical sciences, engineering, and medicine. Topics include: explosions -- from tiny experiments to massive stars; the quirks of flying; why coffee spills; and how rain contributes to the spread of disease among plants.
The meeting will take place November 20-22, 2011, at the Baltimore Convention Center in the historic waterfront district of Baltimore, Maryland. Reporters are invited to attend the conference free of charge. Registration instructions and other information may be found at the end of this news release.
Preliminary Meeting Highlights
SUNDAY, NOVEMBER 20
Fluid Dynamics of Bottle Filling: From large bottles with shampoos and cleaners to small bottles found in the pharmaceutical industry, the filling of bottles is a widely practiced operation in a large number of industries. Researchers will present a primarily computational study of the fluid dynamical challenges that can arise during the rapid filling of bottles.http://meeting.aps.org/Meeting/DFD11/Event/153890
How Mosquitos Fly in the Rain: Raindrops are 50 times heavier than mosquitoes, yet the pesky insects still manage to thrive during rainfall and high humidity. High-speed video reveals that even a bull’s-eye raindrop hit simply pushes past, letting mosquitos buzz along to find their next meal.http://meeting.aps.org/Meeting/DFD11/Event/153906
From a Slow Burn to Supersonic Detonation: The transition from deflagration – a subsonic flame – to a supersonic detonation can occur in environments ranging from experimental and industrial systems on Earth to astrophysical thermonuclear supernovae explosions. http://meeting.aps.org/Meeting/DFD11/Event/154298
Mary Poppins’ Umbrella and the Importance of Being Top-heavy in Flapping Flight: By creating a model system that consists of a pyramid-shaped object hovering in a vertically oscillating airflow, researchers explore how bugs and other flapping flyers use their top-heavy builds to stay aloft. http://meeting.aps.org/Meeting/DFD11/Event/153913
Wind Resource Evaluation for Optimized Wind Energy: As part of a special focus session on wind energy fluid dynamics, researchers evaluate wind resources in order to understand how an array of vertical-axis wind turbines extracts energy from wind. http://meeting.aps.org/Meeting/DFD11/Event/154097
MONDAY, NOVEMBER 21
Walking with Coffee: When and Why It Spills: In our busy lives, almost all of us have to walk with a cup of coffee. Needless to say, under certain conditions we spill that precious liquid. This is a common example of the interplay between the complex motion of a walking individual and the fluid dynamics of a low viscosity liquid contained in a cup.http://meeting.aps.org/Meeting/DFD11/Event/154769
Why Do Things Splash?: The splashing of a droplet when impacting a solid surface is a common, everyday occurrence, but the mechanism for splashing is not well understood. A new analysis gives insight into the subtle dynamics of the splash. http://meeting.aps.org/Meeting/DFD11/Event/154640
Rainfall Suspected Culprit in Leaf Disease Transmission: Rainfalls are suspected to trigger the spread of a multitude of foliar diseases, which could be devastating for agriculture and forestry. Experimental and modeling data shed light on this mode of disease transmission. http://meeting.aps.org/Meeting/DFD11/Event/155026
Sampling Shoes Aerodynamically to Screen for Explosive Materials: Researchers are developing a prototype shoe sampling system that relies on aerodynamic sampling to detect explosive contamination. A new study reveals the fluid dynamics of the proposed system. http://meeting.aps.org/Meeting/DFD11/Event/154681
Water Balloon Bursts! The Science behind the Fun: Throw a water-filled balloon on a rigid surface, pop it with a pin, hold it under water or suspend it in the air. In each case, three dynamic forces conspire to spill the contents in dramatic form. http://meeting.aps.org/Meeting/DFD11/Event/153802
Eggs in Milk: The Conclusion: A hard-boiled egg spinning on a countertop and passing through a puddle of milk draws milk up the side of the egg and then ejects it at the maximum radius. Experimental results are presented on this phenomenon. http://meeting.aps.org/Meeting/DFD11/Event/154451
Nanowires Provide Power for Swimming: A new nanowire motor exploits the flexibility of nanowires for propulsion, with potential biomedical applications.http://meeting.aps.org/Meeting/DFD11/Event/154391
Hydrodynamics of Wine Swirling: A crucial step in wine tasting is the so called “swirling,” necessary to release the bouquet of the wine. This same action is equally crucial in a host of other physics and biology experiments and assays. A new model sheds light on the process.http://meeting.aps.org/Meeting/DFD11/Event/154750
TUESDAY, NOVEMBER 22
Robotic Jellyfish Shows Its Moves: An unmanned underwater vehicle named Robojelly was inspired by actual jellyfish morphology. Researches used its lifelike properties to analyze the mysterious finer points of jellyfish propulsion. http://meeting.aps.org/Meeting/DFD11/Event/155920
Artificial Heart Valves: Better Shapes Mean Better Flow: Mechanical heart valves are extremely important medical devices, yet they are far from ideal. A new prototype with an asymmetric design more closely matches the properties of a natural, healthy heart valve. http://meeting.aps.org/Meeting/DFD11/Event/155922
Supernovas: How Turbulence and Combustion Combine in Stellar Explosions: Type 1a supernovas are cosmic distance markers, so understanding their inner workings is essential for establishing the cosmic yardsticks. New full-star 3-D calculations provide new insights on these cosmic explosions. http://meeting.aps.org/Meeting/DFD11/Event/155293
Bubbles in Drops: From Cavitation to Exploding Stars: In a microgravity experiment, researchers generated single cavitation bubbles inside nearly spherical water drops. They will discuss the possible analogies with various astrophysical processes from our own Sun to asymmetric supernovae.http://meeting.aps.org/Meeting/DFD11/Event/155581

VIRTUAL PRESS ROOM The APS Division of Fluid Dynamics Virtual Press Room will be launched in mid-November and will feature news releases, graphics, videos, and other information to aid in covering the meeting on site and remotely. See: http://www.aps.org/units/dfd/pressroom/index.cfm
GALLERY OF FLUID MOTION Every year, the APS Division of Fluid Dynamics hosts posters and videos that show evocative images and graphics from either computational or experimental studies of flow phenomena. The outstanding entries are selected for their artistic content, originality, and ability to convey information. They will be honored during the meeting, placed on display at the 2012 APS March Meeting, and appear in the annual Gallery of Fluid Motion article in the American Institute of Physics' journal, Physics of Fluids.
Selected entries from the Gallery of Fluid Motion will be hosted as part of the Fluid Dynamics Virtual Press Room. In mid-November, when the Virtual Press Room is launched, another announcement will be sent out.
