✦ Synopsis

A pseudo-spectral scheme for solving the incompressible Navier-Stokes equations using unstructured nodal triangles is proposed. Efficient algorithms are developed with numerical evidence that indicates optimal rates of convergence can be achieved. Navier-Stokes simulations of Kovasznay, shear layer roll up, and flow past a cylinder are included to show comparisons between the different nodal sets considered and an alternative modal approach.

The proposed segregated-implicit (SI) scheme, which is based on the artificial compressibility method, is discretized by the finite difference numerical scheme and verified by simulating a shear-driven cavity flow. The current results demonstrate that the SI scheme is a simple algorithm capable of f
