In recent years, in particular, as a new array of tools have emerged, including a representative amount from the domain of so-called pure mathematics, interest in both the conc

In Chapter 16 we shall employ a zeta function, for example, to provide for a clear mathematical meaning of a certain partition function related to the Hawking path integ

Introduction,he flow of a simple Navier-Stokes fluid. Any extension of the model, however, such as the inclusion of temperature, multiple species or chemical reactions, involves a major research effort. Much remains to be done here. The capability of these methods in resolving complex geometries is, however, uns

Flow and diffusion in random porous media from lattice gas simulations,n an image analyzer:.Using the F.H.P. model with six velocities on the hexagonal grid, and appropriate boundary conditions, flows in samples with infinite length are simulated, reproducing Poiseuille‘s flow conditions. Similar lattice gas experiments produced on random porous media simulations enabl

Darcy flow in porous media: Cellular automata simulations, based on a Navier-Stokes automaton (Frisch, et al.). Darcy characteristics are brought in with the help of so-called scatter cells. The convergence is speeded up by a kind of multi-grid technique. The two-phase automaton is based on diffusion-limited aggregation (DLA). In this automaton ‘voids’ are
