| Abstract: |
| The Hartmann number in the nondimensional control equations may lead to divergence or larger error for numerical simulation.The meshless Galerkin method is applied to compute the steady maneto hydrodynamic flow in rectangular insulated duct.A steady technique is introduced into the Galerkin method due to the large error problem caused by the large Hartmann number in maneto hydrodynamic flow control equations.Numerical results show that errors from meshless Galerkin method with steady technique are less than that from standard Galerkin method.And maneto hydrodynamic flow in insulated duct with Hartmann number over 50000 may be well simulated with the impoved method. |
