Schedule for the APS DFD Press Conferences with Live Webcasts from Seattle

Press conferences for the 72nd Annual Meeting of the American Physical Society Division of Fluid Dynamics in Seattle will be held Monday, Nov. 25, at the Washington State Convention Center. The conferences, which will be webcast, will focus on research into how flow control is making some MLB pitchers nearly unhittable, predicting tornado formation from the sounds that storms make and teaching fluid mechanics through dance, as well as other discoveries in fluid dynamics.

Fluid Dynamics Provides Insight into Wildfire Behavior

The Kincade Fire has been burning through Sonoma County, displacing people from their homes and leaving destruction in its wake. It is a stark reminder of the increasingly pressing need for a better understanding of how fires begin and spread. This is where Rodman Linn and his research come in. He develops and uses computational models of the coupled interaction between the wildfires and surrounding atmosphere at Los Alamos National Laboratory. In the November 2019 issue of Physics Today, Linn describes a few of the many ways that fluid dynamics controls the behavior of fires.

Analysis of Galileo’s Jupiter Entry Probe Reveals Gaps in Heat Shield Modeling

The entry probe of the Galileo mission to Jupiter entered the planet’s atmosphere in 1995 in fiery fashion, generating enough heat to cause plasma reactions on its surface. The data relayed about the burning of its heat shield differed from the effects predicted in fluid dynamics models, and new work examines what might have caused such a discrepancy.

Stabilizing Multilayer Flows May Improve Transportation of Heavy Oils

During the past 20 years, the oil industry has begun to transition away from light oils toward heavier oils. But transporting heavy oils cost-effectively is a challenge because heavy oils are viscous — essentially a thick, sticky and semifluid mess. One way to outmaneuver this problem, reported in Physics of Fluids, is a viscoplastic lubrication technique.
