Modelling the interaction of small and large eddies in a turbulent flow is an important part of the understanding of turbulence and an important task in subgrid modelling and computational fluid dynamics. In this article we describe a new approach to this problem based on dynamical systems theory:
A new numerical formulation is proposed in this investigation for the solution of parabolic differential equations. The time step parameter 1 = ~AT/(Ax)' under consideration is as large as 2000 such that only a few time steps are needed for the entire regime of transient heat conduction. Along with
