SUMMARY:Aphros: High Performance Software for Multiphase Flows with Large 
 Scale Bubble and Drop Clusters
DESCRIPTION:Paper\n\nAphros: High Performance Software for Multiphase Flow
 s with Large Scale Bubble and Drop Clusters\n\nKarnakov, Wermelinger, Litv
 inov, Koumoutsakos\n\nWe present the high performance implementation of a 
 new algorithm for simulating multiphase flows with bubbles and drops that 
 do not coalesce. The algorithm is more efficient than the standard multi-m
 arker volume-of-fluid method since the number of required fields does not 
 depend on the number of bubbles. The capabilities of our methods are demon
 strated on simulations of a foaming waterfall where we analyze the effects
  of coalescence prevention on the bubble size distribution and show how ri
 sing bubbles cluster up as foam on the water surface. Our implementation e
 nables high throughput simulations of multiphase flow, supports distribute
 d as well as hybrid execution modes and scales efficiently on large comput
 e systems.\n\nDomain: CS and Math, Physics, Life Sciences
