Development of a generalized model of heat-mass transfer between fuel drops and gas stream with reference to gas turbine engine combustion chambers

Abstract


The paper presents a generalized model of heating and evaporation of separate fuel drops, taking into account the influence of the distribution of fuel steam concentration around the drop on the evaporation process. Numerical calculations for the operations typical for gas turbine engine combustion chambers are presented. The range of air flow temperatures over which the influence of fuel steam concentration in the drop environment on the rate of its evaporation and the fuel distribution in the swept volume of the combustion chamber is significant has been defined.
