Simulation of drop coagulations in swirled time dependent streams with reference to gas turbine engine combustion chambers

Abstract


The paper presents a model of fuel drop coagulation with reference to gas turbine engine combustion chambers. Calculations of drop coagulation are carried out at various values of the fuel spray expansion angles and initial drop sizes using the model developed. The values of drop concentrations and their sizes depending on geometrical and performance characteristics of the sprayer are specified. It is shown that the decrease of the fuel spray angle, with the initial drop concentration and their sizes being the same, leads to the shift of the fuel concentration maximum towards larger sizes and increase in drop concentrations.
