报告题目:A unified framework of the SAV-ZEC method for a mass-conserved Allen-Cahn type two-phase ferrofluid flow model
报告摘要:We develop a mass-conserved Allen--Cahn type two-phase ferrofluid flow model. To efficiently solve this model, we also develop a unified framework of the scalar auxiliary variable (SAV) method and the zero energy contribution (ZEC) approach. Then, we construct a mass-conserved, fully decoupled, second-order accurate in time, and unconditionally energy-stable linear scheme.
