A Second Order Defect Correction Scheme for Unsteady Problems
Abstract : Using the defect correction method (DeC), we propose an implicit scheme that is second order accurate both in time and space,but that uses only first order jacobian. In a first time, we theoretically analyse the truncation error of the scheme and perform a linear stability analysis of it. Then some numerical experiments over simple test-cases are presented. Finally, the capability and accuracy of this new scheme is outlined by the analisys of a complex unsteady flow in a 2-D model of a piston engine.
