This paper proposes an integrated model of the behavior of a nonbuoyant jet injected into a uniform cross flow. Governing equations are the integrated conservation equations of mass, cross-streamwise and its perpendicular components of momentum. The ordinary differential equations to predict the variations of cross-sectional area, mean velocity, and the trajectory of a jet axis are derived from the governing equations. In the present model, the interaction between the jet and cross-flow are taken into account by considering form drag and entrainment of the ambient fluid. A new type of entrainment function is proposed. Jet trajectory computed using the present entrainment function shows good agreement with experimental data.
