The left image in the animation is of bubbles forming at a jet located near the wall of a fluidised bed. The wall is heated and the CFD model predicts heat transfer between the wall and bed. The instantaneous heat transfer coefficient is plotted, along the wall, in the right image.
If the animation does not load or is of poor quality, try running this compiled Smacker file: f6.exe (0.5MB).
Note that this is an executable file, and should be suitable for all PCs running Win95 or later. For more information about Smacker and its compiled executables, please follow this link.
