Study of combustion processes in the combustion chambers of power facilities

摘要

Simulation of the aerodynamic structure of the flow with a reasonable choice of the turbulence model makes it possible to obtain adequate results with sufficient accuracy for practice.In the proposed article,when studying the processes of heat and mass transfer,we focused our attention on the chosen turbulence model and used the results of the aerodynamic structure to explain the flow of mass flows of nitrogen oxides throughout the space of the combustion chamber.As a result of 3D computational calculations,the distributions of turbulence parameters {k and s),velocity field(total velocity vector and its components)and nitrogen oxides in the volume of the combustion chamber and at its outlet were obtained.These results will make it possible to effectively control the processes of fuel combustion in real power plants and solve urgent problems of thermal power engineering and ecology.
