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. This image shows a section of a channel wall near a rib. Isosurfaces of instantaneous, coherent vorticity created by shear layer instabilities on the rib enhance mixing and heat transfer. The regions of coherent vorticity are correlated to regions of high heat transfer (blue) on channel walls. Hot spots (red) are found at corners and immediately behind the rib. The software used in producing these simulations was developed with support of a National Science Foundation grant. [Image 1 of 3 related images. See Image 2.]
