abstract = {<p style="text-align: justify;">We develop a stabilizer free weak Galerkin (SFWG) finite element method for Brinkman
equations. The main idea is to use high order polynomials to compute the discrete weak
gradient and then the stabilizing term is removed from the numerical formulation. The
SFWG scheme is very simple and easy to implement on polygonal meshes. We prove
the well-posedness of the scheme and derive optimal order error estimates in energy and $L^2$ norm. The error results are independent of the permeability tensor, hence the SFWG
method is stable and accurate for both the Stokes and Darcy dominated problems. Finally,
we present some numerical experiments to verify the efficiency and stability of the SFWG
method.</p>},
