Abstract

This work aims at observing the effect of the mortar element method applied to a geometry requiring refinement in the vicinity of singularities induced by the presence of sharp corners. We solve the two-dimensional incompressible Navier–Stokes equations with a spectral element method. Mortar elements allow for local polynomial refinement, since they allow for functional nonconformity. The problem solved is the flow in a channel partially obstructed by an obstacle representing a rectangular blade.
