Direct numerical computation of disorder parameters

High performance computation for direct numerical and large eddy simulation

This paper focusses on high order compact schemes for direct numerical simulation (dns) and large eddy simulation (les) for flow separation, transition, tip vortex, and flow control. We discuss the fundamental issues of high quality grid generation, high order schemes for curvilinear coordinates, the cfl condition for complex geometry, and high-order weighted compact schemes for shock capturing...

Numerical Computation of Canards

Singularly perturbed systems of ordinary differential equations arise in many biological, physical and chemical systems. We present an example of a singularly perturbed system of ordinary differential equations that arises as a model of the electrical potential across the cell membrane of a neuron. We describe two periodic solutions of this example that were numerically computed using continuat...

Numerical Computation of Normal

In this paper we introduce a general methodology for computing (numerically) the normal form around a periodic orbit of an autonomous analytic Hamiltonian system. The process follows two steps. First, we expand the Hamiltonian in suitable coordinates around the orbit and second, we perform a standard normal form scheme, based on the Lie series method. This scheme is carried out up to some nite ...
