Property of a fluid to form droplets and assume the shape of a sphere and rise in a capillary tube. Previous work on cast alloys has shown that the relationship between solidification time (θ) and casting geometry obeys the Chvorinov law , : (1) θ = 1 K 2 (V vol A area) 2 where K is the solidification constant, and V vol and A area are the volume and surface area of casting respectively. Although Fluent offers more in-built functionalities to do this, it is quite difficult to achieve something beyond. Given that the large majority of the calculation time was employed by both programs to perform the DEM calculations, it may be concluded that the particle-related algorithm of MFiX is more efficient.

Compressible flow (or gas dynamics) is the branch of fluid mechanics that deals with flows having significant changes in fluid density.While all flows are compressible, flows are usually treated as being incompressible when the Mach number (the ratio of the speed of the flow to the speed of sound) is smaller than 0.3 (since the density change due to velocity is about 5% in that case).

In MFiX, two interpolation schemes can be employed: one based on the grid size, and one based on a user-specified interpolation width, which is recommended to be set equal to the particle size. Rev.
