For a theory of turbulent premixed flames to be useful in practical circumstances, it needs to employ few parameters to describe the governing factors concerning fluid flow and chemical reaction and, furthermore, their nature should be readily comprehensible. In this paper is presented a theory which requires a knowledge only of the turbulent kinetic energy and its rate of dissipation to describe the turbulence, and only of laminar burning velocity to describe the chemical system. One further parameter is required to describe the interaction between turbulence and combustion. The theory is a purely wrinkled-flame treatment which allows the calculation of the growth of total flamelet area by combining the effects of turbulent wrinkling with those of changes in mean geometric shape. It is a feature of the treatment that a turbulent burning velocity cannot be a characteristic of a turbulent flame in the way that laminar burning velocity is a laminar flame.
