Abstract
The covariance transformation used in earlier theoretical studies of turbulent-flame and isothermal-front propagation is defined and mathematically derived. This transformation provides the covariance associated with fluctuations of a turbulent scalar or vector-component variable in terms of the statistical properties of another fluctuating scalar or vector-component variable when the Fourier transforms of the two variables in transverse-wave number and frequency space are linearly dependent.
Key words: Covariance, turbulence, turbulent combustion, front propagation, flame propagation
