A Stabilized Mixed Finite Element Method for Single-Phase Compressible Flow

الملخص EN

We present and study a stabilized mixed finite element method for single-phase compressible flow through porous media.

This method is based on a pressure projection stabilization method for multiple-dimensional incompressible flow problems by using the lowest equal-order pair for velocity and pressure (i.e., the P1−P1 pair).

An optimal error estimate in divergence norm for the velocity and suboptimal error estimates in the L2-norm for both velocity and pressure are obtained.

Numerical results are given in support of the developed theory.
