Discrete unified gas kinetic scheme simulation of conjugate heat transfer problems in complex geometries by a ghost-cell interface method

作者:

Highlights:

• DUGKS is advanced to the simulation of conjugate heat transfer problems.

• The ghost-cell scheme is used to handle the curved conjugate interface.

• With unknown distribution function corrected, the interface is captured clearly.

• The versatility of the method is tested in some complex conjugate thermal flows.
