Mathematical model of upper-atmosphere winds and planetary temperatures
J. Scroggs, F. Semazzi, G. Pouliot

The figure shows results from a global circulation model prediction. The spectral colors in the streamlines correspond to temperature from –50 C in dark purple to 0 C in medium orange. Jet streams can be seen where the streamlines merge.

 

 

Numerical simulation of granular flow in hoppers
P. Gremaud, J. Matthews

The figure shows a granular material, such as cereal grains, inside a silo. The material is being discharged through an outlet at the bottom of the hopper. The colors correspond to stress distributions and illustrate the effect of discontinuities at the hopper walls on the flowing properties of the structure. The goal is eventually to explain why such flows may be irregular or stop entirely in practice.
