Higher-Order Compact-Flow Field-Dependent Variation (HOC-FDV) method for solving two dimensional navier-stokes equation
In this article, a new, higher-order accurate method, namely higher-order compact-flow field-dependent variation (HOC-FDV) method, has been developed to solve two-dimensional Navier�Stokes equations. The HOC-FDV scheme is of third-order accu�racy in time and fourth-order in space. The spatial deri...

| description | In this article, a new, higher-order accurate method, namely
higher-order compact-flow field-dependent variation (HOC-FDV)
method, has been developed to solve two-dimensional Navier�Stokes equations. The HOC-FDV scheme is of third-order accu�racy in time and fourth-order in space. The spatial derivatives in
the flow field-dependent variation (FDV) equations proposed by
Chung are approximated using higher-order compact (HOC) Her�mitian (Pade) scheme. The solution procedure at each time step
consists of a system of block tri-diagonal matrices which can be
solved efficiently in a standard manner. Several numerical exam�ples are tested to examine the accuracy and capability of the new
scheme to capture the shock and to simulate accurately separation
and discontinuity |
