 thod for miscible displacement in heterogeneous porous media\n\n\nAbstract
 :\nWe present a cell centered Galerkin (CCG) method applied to miscible di
 splacement problems in heterogeneous porous media. The CCG approach combin
 es concepts from finite volume and discontinuous Galerkin (DG) methods to 
 arrive at an efficient lowest-order approximation (one unknown per cell). 
 We demonstrate that the CCG method can be defined using classical DG weak 
 formulations, only requires one unknown per cell, and is able to deliver c
 omparable accuracy (to piecewise linear DG) and improved efficiency over t
 raditional higher-order interior penalty DG methods. An interesting featur
 e of the CCG method is that it obeys a maximum principal property. A pleth
 ora of computational experiments in 2D and 3D showcase the effectiveness o
 f the CCG method for highly heterogeneous flow and transport problems in p
 orous media.\n
