Whether in airplane engines or power plants, turbine blades are often subjected to extremely high temperatures. The blades are cooled internally with cold air flowing through serpentine channels. To enhance the rate of cooling, roughness elements, or ribs, are placed in the channels to generate turbulence. This image plots instantaneous velocity streamtubes and temperature on channel walls. The intertwined nature of streamtubes is a result of strong mixing in the flow. The software used in producing these simulations was developed under a National Science Foundation grant.

More about this Image This simulation was created by Danesh Tafti and Randy Heiland of the National Computational Science Alliance (NCSA) at the University of Illinois at Urbana-Champaign, using GenIDLEST computational fluid dynamics software and NCSA VisBench, a visualization system. Research represented in the visualization of the multilouvered fin is supported by the Air Conditioning Refrigeration Center at the University of Illinois at Urbana-Champaign.
