Non-intrusive reduced order modelling of the NavierStokes equations
This is the first work to apply two non-intrusive ROMs for solving the NS equations. A second order Taylors series method for calculating the POD coefficients. A Smolyak sparse grid collocation method for calculating the POD coefficients. Implementation of the non-intrusive ROMs does not require modifications to a system code. Ability of non-intrusive ROMs to capture the highly nonlinear fluid dynamics.
