Abstract
This paper presents an approach for modeling a liquid jet trajectory in a subsonic gaseous crossflow. Forces acting on the liquid column including drag, gravitation, surface tension, and viscosity are all accounted for along with the mass and energy conservation equations which are employed to model the liquid jet trajectory. The tangential and normal components of the governing equations are solved analytically using control-volume analysis. A novel correlation in a sinusoidal-exponential functional form is developed as a function of the momentum flux ratio, gas and jet Weber number, jet Reynolds number, and Bond number. This correlation is capable of predicting jet trajectory of different liquids in a subsonic crossflow at different operating conditions and injection angles. The predictions showed reasonable agreement with published experimental data and empirical correlations.
