Abstract

The results of experimental studies of the fine structure of the spectra of molecular absorption and emission of combustion products of energetic fuels and their application in solving problems of radiative heat transfer in structurally inhomogeneous multicomponent media are considered. The methods of determining the parameters of the spectral absorption lines from the experimental emission spectra of the flame in the combustion products of gas fuel the identification of optically active ingredients in the combustion products and anthropogenic emissions into the atmosphere are analyzed. Attention is drawn to the fact that the emission of gas components is selective and the methods for calculating the radiative heat exchange in the combustion chambers of power units must take into account the acute selection of the molecular absorption spectra of radiation.

Highlights

Solving problems of radiative heat transfer in the combustion chambers of power units requires knowledge of the radiation characteristics of the optically active ingredients of the gas and dispersed phase of the combustion products
For the gas phase of the combustion products the main radiation characteristic is the spectral transmittance function (STF) which depends on temperature in a complex way and is determined by the fine structure of the absorption spectra of the combustion products
Strict solutions of the problems of radiative heat transfer in a structurally inhomogeneous medium require taking into account the acute selection of absorption spectra and its dependence of the temperature of the ingredients of the gas phase of the combustion products

Summary

Introduction

Solving problems of radiative heat transfer in the combustion chambers of power units requires knowledge of the radiation characteristics of the optically active ingredients of the gas and dispersed phase of the combustion products. For the gas phase of the combustion products the main radiation characteristic is the spectral transmittance function (STF) which depends on temperature in a complex way and is determined by the fine structure of the absorption (emission) spectra of the combustion products.
