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.
