In his presentation to the 61st APS Division of Fluid Dynamics in San Antonio, Plesniak will describe his team's research and how it is also helping to create a computational turbulence simulation software tool that airplane manufacturers and safety regulators could use to model complex, realistic cabin ventilation scenarios more rapidly and economically than is now possible. The tool could also be used to design ventilation systems for interiors of buildings, subways and tunnels.
Plesniak's talk, "Experimental Model of Contaminant Transport by a Moving Wake Inside an Aircraft Cabin," will be given at 5:06 p.m. on Monday, November 24, 2008, in Room 002A of the San Antonio Convention Center. Abstract: http://meetings.aps.org/Meeting/DFD08/Event/90679
6) PULSATING JETS MAY IMPROVE JET ENGINE PERFORMANCE AND EFFICIENCY
Actions similar to those of a pulsating water-massage shower head may lead to more effective control of rocket engines and cleaner, more efficient jet aircraft engines, UCLA scientists have discovered.
In her presentation to the 61st Annual Meeting of the APS Division of Fluid Dynamics in San Antonio, Juliett Davitian will describe new research into the behavior of "transverse" jets, which consist of gas or liquid injected into a crossflow of a similar fluid. Engine manufacturers use transverse jets to introduce gases into jet engines for reducing emissions or cooling the turbine blades. These jets are also used to control the thrust of rocket engines.
In some applications, rapid and thorough mixing of the jet and crossflow fluids is needed. In other cases, deep penetration of the jet into the crossflow is desired. Sometimes both characteristics are required. B
