NASA CFD Software Helps Quiet the Skies

Contributed by: Dr. Craig Hunter, NASA Langley When Denver International Airport (DIA) joined the nation’s commercial air transport system in 1995, property owners in rural Adams County, a community 15 miles east of DIA, were concerned about the increase in noise that accompanied the new airport. A quick remedy to DIA’s noise problem is re-routing arriving and departing aircraft around populated areas. As the nation¹s fifth busiest airport, however, DIA quickly […]

Plot of the month: The evolution of coronal loops

Contributed by Mayya Tokman, Ph.D., Visiting Assistant Professor Department of Mathematics, University of California, Berkeley Plasma Plasma is a distinct state of matter containing electrically charged particles that affect its electrical properties and behavior. In addition to being important in many aspects of our daily lives, plasmas may constitute more than 99 percent of the visible universe. Plasma is often called the fourth state of matter, the other three being […]

Plot of the month: Melbourne cricket ground redevelopment

Contributed by Eric Jal, Sr. Engineer, Energy Div. Connell Wagner, Melbourne, Australia Ventilation is a key design factor for the new Melbourne Cricket Ground (MCG). Using PHOENICS to optimize the design, CFD and Tecplot have been used to analyze air movement within the building and in external areas. In this image we see relative changes in air movement patterns across the pitch due to the construction of the new Northern […]
