CREBCOM code system for description of gaseous combustion

An approach is presented to combine a system of criteria and combustion mod els into a computer tool for conservative estimates of possible pressure lo ads resulting from combustion of fuel-air mixtures. This approach is based on identification of characteristic combustion regimes by their relative se verity, application of criteria to identify the strongest possible regime f or particular initial conditions and geometry, and on development of approp riate three-dimensional models to describe flame propagation and loads for selected combustion regimes. A computer code (CREBCOM) was developed using this approach. Short descriptions of the code, criteria and models are give n. The computer code was applied to simulate turbulent deflagration and det onation experiments at different scale and geometrical configurations. Thes e experiments included tests with flame propagation in explosion channels ( tubes) and large-scale tests in the RUT facility. Numerical simulations sho wed that such a code is able to give reliable estimations of overpressure f or a wide range of combustion regimes, compositions and geometry. (C) 2001 Elsevier Science Ltd.
