abstract = {<p style="text-align: justify;">In this paper, the discrete unified gas-kinetic scheme (DUGKS) is extended
to the convection heat transfer in porous media at representative elementary volume
(REV) scale, where the changes of velocity and temperature fields are described by
two kinetic equations. The effects from the porous medium are incorporated into
the method by including the porosity into the equilibrium distribution function, and
adding a resistance force in the kinetic equation for the velocity field. The proposed
method is systematically validated by several canonical cases, including the mixed
convection in porous channel, the natural convection in porous cavity, and the natural convection in a cavity partially filled with porous media. The numerical results
are in good agreement with the benchmark solutions and the available experimental
data. It is also shown that the coupled DUGKS yields a second-order accuracy in both
temporal and spatial spaces.</p>},
