Velocity Streamtubes
Caption:
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 place 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.
