Emergence-Based approach to computational fluid dynamics

Jankovic, L.

Abstract

Computational Fluid Dynamics (CFD) modelling
requires considerable user preparation time and
considerable CPU time for reproducing the simplest
of behaviours of air movement in and around
buildings. This is due to the top-down approach to
modelling, in which the system is described with
Navier-Stokes simultaneous differential equations,
generating large solution space. This paper
investigates a radically different approach, in which
the system is modelled from the bottom up, thus
avoiding the need for Navier-Stokes equations whilst
still relying on the same fundamental principles. The
paper discusses how this approach can change the
culture and the practice of building simulation, with a
potential to make sketch drawings become alive and
enable hourly time-stepped annual CFD simulations
to be conducted on personal computers.
