We describe some Hermite stream function and velocity finite elements and a divergence‐free finite element method for the computation of incompressible flow. Divergence‐free velocity bases defined on (but not limited to) rectangles are presented, which produce pointwise divergence‐free flow fields (∇·uh≡0). The discrete velocity satisfies a flow equation that does not involve pressure. The pressure can be recovered as a function of the velocity if needed. The method is formulated in primitive… 
Simple Finite Element Numerical Simulation of Incompressible Flow Over Non-rectangular Domains and the Super-Convergence Analysis
The dynamical mechanism of the boundary layer separation for a triangular cavity flow with Reynolds numbers, including the precise values of bifurcation location and critical time, are reported in this paper.
A Combination of a Special Hermite Finite Element with Collocation for a Reaction-Diffusion Type Equation
In the paper, we propose an efficient method based on the use of a bicubic Hermite finite element coupled with collocation for the reaction-diffusion equation with a variable coefficient. This

Efficient finite element methods for aircraft engine noise prediction
Aircraft noise has a negative environmental impact. One of the ways in which it can be mitigated is by placing acoustic liners inside the aircraft's engines. These liners can be optimised for noise


A test problem for outflow boundary conditions—flow over a backward-facing step
A numerical solution for steady incompressible flow over a two-dimensional backward-facing step is developed using a Galerkin-based finite element method. The Reynolds number for the simulations is

A Galerkin–Lagrange multiplier formulation is used for the numerical solution of the stationary Navier–Stokes equations, in order to avoid the construction of zero-divergence elements. The
A short note on the reattachment length for BFS problem
The standard backward-facing step flow problem is solved for steady state laminar case using stream function-vorticity method. The steady state results are obtained as the asymptotic solution of the

We use a one-dimensional model problem of advection– diffusion to investigate the treatment recently advocated by Papanastasiou and colleagues to deal with boundary conditions at artificial outflow
Résumé and remarks on the open boundary condition minisymposium
The two minisymposia on OBCs that are summarized in this paper had the objective of finding the best OBC's for a small subset of two-dimensional test problems, but the contributions obtained probably raised many more questions/issues than were resolved.
Previous developments in the direct stiffness method are reviewed. The advantages of extending the definitions to make the method a variational approach are cited. The finite element formulation of
