This paper consists of an analysis of existing methods and their limitations pertaining to defining the dissipation rate as one of the components of the turbulent kinetic energy balance equation. Careful attention has been paid with reference to the method used during tests conducted in a burning round jet by means of laser Doppler anemometry. This paper covers the developed algorithms for digital signal processing of LDA, examples of output data sets for calculations and chosen profiles of energy balance components of dissipation and production.
