摘要：

We present new parameter-free superconvergent H(div)-conforming  HDG methods for the Brinkman equations on both simplicial and rectangular meshes  using a velocity gradient-velocity-pressure formulation. We obtain an optimal  L2-error estimate for the velocity in both the Stokes-dominated and  Darcy-dominated regimes.  Moreover, thanks to H(div)-conformity of the velocity,  the velocity error estimates are independent of the pressure  regularity.
