Boyce Single Bubble

+

Qualitative Benchmarking: Single bubble injection

+
+
+
+
+ +
+
+
+ Recent experiments + by C.M. Boyce and coworkers considers the rapid, high-speed injection + of a single bubble into an incipiently fluidized bed. Here, the 50 m/s jet is turned on + for 150 ms causing a single large bubble to form, rise through the 3 mm particle bed and + erupt a the surface. Ovito animaiton shows particles in + the center 10 mm thick slice of the 190 mm diameter bed, colored by their vercial + velocity ranging from -0.3 m/s (black) to 1.0 m/s (white). + Simulation models 260K particles with MFiX-Exa 19.08 using 32 CPU cores. +

Granular Rayleigh-Taylor

+

Qualitative Benchmarking: Gravitational granular flow instability

+
+
+
+ The "granular" variant of the classical RT instability superimposes an assemply of + 1.12M random loose packed particles over air. The instability finger/bubble pattern + which reaches a (statistical) equilibrium between coarsening via finger merging and + refinement via bubble splitting. Black and white ovito + animation shows particle location. + Simulation performed with MFiX-Exa 19.08 238 16 CPU cores. +
