The aim of this work is to study the characteristics of high-temperature flame in the burning device during combustion of diesel fuel with steam gasification for understanding the basic mechanisms of the reaction and the role of physical factors.

Experimental study of flame characteristics during the combustion of certain types of liquid hydrocarbon fuels

The paper represents experimental studying the scales of turbulent vortices in diffusion flames by using the measurements of thermodynamic characteristics obtained by thermography and the aerodynamic characteristics obtained by the PIV method.

Experimental and numerical study of temperature fields and flows in flame during the diffusion combustion of certain liquid fuels

The paper represents experimental studying the pulsations of temperature fields and the structure of a flow in the flame formed during the combustion of certain fuels. Also, the paper provides the mathematical modeling of a flow in the flame formed during the combustion of diesel fuels, as well as the comparison with experimental data and the estimation of the scale for turbulent vortices in flame. The experimental results are in satisfactory agreement with numerical modeling, which confirms the hypothesis of similarity for the pulsations of hydrodynamic and thermodynamic parameters.

The Method of Manufacturing Nonmetallic Test-Blocks on Different Sensitivity Classes

Nowadays in our modern world there is a vital question of quality control of details made from nonmetallic materials due to their wide spreading. Nondestructive penetrant testing is effective, and in some cases it is the only possible method of accidents prevention at high- risk sites. A brief review of check sample necessary for quality evaluation of penetrant materials is considered. There was offered a way of making agents for quality of penetrant materials testing according to different liquid penetrant testing sensibility classes.
