The convection term evaluation of the turbulence kinetic energy balance in a flame with medium density changes

Abstract

This paper consists of an analysis pertaining to the turbulence kinetic energy balance equation with the acknowledgement of burning medium density change influence. The evaluation of the convection element value and of the density change influence on the turbulence kinetic energy balance has been attempted. Experimental data obtained by means of laser Doppler anemometry and the radial distributions of average temperatures of a burn- ing jet have been exploited in the present paper.
