-------- ABSTRACT ---------

EXPLOITS is a customised version of the PHOENICS flow-simulation software package, which is being developed by CHAM during 1996, for the prediction of:-

EXPLOITS is an acronym for EXPLOsIon and blasT Simulator.

EXPLOITS differs from other ostensibly-similar software packages by way of:-

EXPLOITS is also supplied with novel and unique turbulence and combustion models, which enable it to replace guesswork by computation in important parts of the prediction process.

One feature of these models is that they permit numerical-error estimates to be made.

However, EXPLOITS is not claimed by CHAM to be able to do more than indicate what will PROBABLY happen.

The reasons are that the science of turbulence, whether the fluid is reactive or inert, is not sufficiently far advanced to make certainty justifiable, even in much more simple circumstances than those of off-shore oil platforms.

The wise user of EXPLOITS therefore keeps in mind two mnemonics:
NOKFOS (meaning NObody Knows FOr Sure); and
BATWEC (meaning Best Available Technique Without Excessive Cost).

"Because of NOKFOS, EXPLOITS represents the BATWEC"
