We have seen
the equations. Now we need to discretize them, by means of the final element
discretization, again we use Galerkin's procedures and come up with the
linear momentum balance equation, then we have the two mass balance equations
for gas and water. The system of equation is non-linear, is non-symmetric and is coupled, because we have orthodiagonal matrix. We can collect this matrix in ipomatrixes and can obtain and write a system of equations in a concise form. | ![]() |
