The method of "random vortices" is used to describe the                         generation and later behavior of turbulence in a chemically                     reacting flow.  This method avoids the steady state assumption                  which weakens existing models of turbulence.  Although it has some              limitations, it is one of the most promising steps forward in                   the numerical analysis of reacting flow fields.  An extensive                   range of Reynolds and Peclet numbers will be tested in various                  configurations, with a view to identify and predict such critical               phenomena as stability, extinction, flame stretch, swirl effect,                etc...  As the field stands today, large sets of experimental                   data are waiting to be used for the verification of such improved               comprehensive numerical models.                                                                                                                                 The availability of a reliable predictive model in turbulent                    reacting flow fields has been an elusive goal to the combustion                 community.  During the last twenty years a number of simplified                 numerical models have been tried but with little generic                        success.  This new method introduces vorticity as a fundamental                 aspect of turbulence generation; in earlier times insufficient                  computer performance had ruled out this important refinement.                   Success in the development of this program would open the way for               computer codes of increased flexibility and generality.
