The least–square/fictitious domain method based on Navier slip boundary condition for simulation of flow–particle interaction
作者：
Highlights：
• We develop a least-squares/fictitious domain method for direct simulation of fluid particle motion with Navier slip boundary condition at the fluid-particle interface.
• We propose and implement an explicit-implicit scheme for the coupled system.
• We numerically compare our results with Jeffery obit and verify the slip effect.
