SUMMARY:An Impulse Ghost Fluid Method for Simulating Two-Phase Flows
DESCRIPTION:Yuchen Sun (Georgia Institute of Technology); Linglai Chen (Ha
 rvard University); Weiyuan Zeng (Zhejiang University); Tao Du (Tsinghua Un
 iversity, Shanghai Qi Zhi Institute); Shiying Xiong (Zhejiang University);
  and Bo Zhu (Georgia Institute of Technology)\n\nThis paper introduces a t
 wo-phase interfacial fluid model based on the impulse variable to capture 
 complex vorticity-interface interactions. Our key idea is to leverage bidi
 rectional flow map theory to enhance the transport accuracy of both vortic
 ity and interfaces simultaneously and address their coupling within a unif
 ied Eulerian framework. At the heart of our framework is an impulse ghost 
 fluid method to solve the two-phase incompressible fluid characterized by 
 its interfacial dynamics. To deal with the history-dependent jump of gauge
  variables across a dynamic interface, we develop a novel path integral fo
 rmula empowered by spatiotemporal buffers to convert the history-dependent
  jump condition into a geometry-dependent jump condition when projecting i
 mpulse to velocity. \n\nWe demonstrate the efficacy of our approach in sim
 ulating and visualizing several interface-vorticity interaction problems w
 ith cross-phase vortical evolution, including interfacial whirlpool, vorte
 x ring reflection, and leapfrogging bubble rings.\n\nRegistration Category
