To calculate the trajectory and coordinates of the droplets, the time of their flight, it is necessary to determine the parameters of droplet evaporation and their concentration in the stream. After the nozzle passes, the droplets move along different trajectories and form a fuel torch. The trajectory of the torch droplets is calculated according to the given initial parameters of the droplets, as well as the parameters of the nozzle and taking into account their influence on the movement of the droplet The aim of this work is to calculate the temperature of the evaporating droplet layer, which is necessary for calculating the trajectory and time of the droplet's motion depending on the thermodynamic parameters of the fuel. Based on the obtained air and fuel vapor parameters, the temperature of the evaporating droplet layer is found, which is necessary for calculating the trajectory, coordinates and time of movement of the fuel droplets after the nozzle.
