Effect of Low Ambient Pressure on Spray Cone Angle of Pressure Swirl Atomizer
International Journal of Aerospace Engineering, Volume 2021, Issue 1, 2021., 2021 Pressure swirl atomizers are widely used in gas turbine combustor; this paper is aimed at researching the effect of low ambient pressure (0.1 MPa to 0.01 MPa, lower than an atmosphere) on the spray cone angle of pressure swirl atomizer. The spray angle is captured by high‐speed photography; then, an image post program is used to process the spray angle
