### 6.6 The probabilistic (Monte-Carlo) approach

Another approach to the modelling of turbulent flows, and
especially those involving combustion, is the probabilistic method.

This employs a Monte-Carlo technique which enables a probability-
density function to be constructed if a sufficiently large number
of "particles" is employed.

Although this is not supplied with the current PHOENICS (and
perhaps, because of the seeming superiority of MFM, never will be),
it should be noted thet a recent paper has been published which
shows how the PHOENICS can be used as the basis for Monte-Carlo
calculations (Fueyo, Larroya, Valino and Dopazo,1995).

Some remarks similarities and differences between the probabilistic
and MFM approaches may be found in the PHENC entry: Multi-Fluid
Models of Turbulence.
