Evaluation<br />

• Porosity not constant<br />

• Function of t<br />

• Therefore also function of r<br />

• Change in gas-density<br />

• Temporal effects<br />

• When is the stationary solution relevant<br />

• Temporal simulations can be done (validate latter)<br />

• Valid for shrinking sphere as well<br />

• Change position of boundary condition as function of<br />
