Abstract
The iterative solution of the governing transport
equations for momentum, heat and mass transfer in flowing fluids can
be very difficult. These difficulties arise from the nonlinear,
coupled, nonsymmetric nature of the system of algebraic equations
resulting from numerical approximation of the PDEs. This talk focuses
on evaluating a number of preconditioned Krylov methods for solution
of the Navier-Stokes equations with heat and mass transport. Our
discussion considers efficiency, robustness and implementation issues
for fully-coupled solutions methods.
