3D Cooling Jets


Using a Refinement Object

The movies in this section show how I was able to limit the refinement using a refinement object which travels with the head of the jet. These simulations are old ones from when I was still simulating the full 3D grid. I have since simplified the problem by taking advantage of some symmetries. Current set ups simulate a quarter of the grid, and can be run in both 2D and 2.5D (cylindrical coordinates with axial symmetry).

Note that the color bar is different for the volume rendering in order to see through the ambient.



Moderate Cooling
