Deflected heated water jets, theory and experiments
Abstract
A simple one dimensional mathematical model based on an entrainment concept was developed. The entrainment function is assumed to depend on the distance along the jet axis, the jet and ambient flow velocity ratio and the jet entry. Equations representing the conservation of mass, momentum and heat are integrated in a closed form. Experiments were conducted in a rectangular open channel at various jet to ambient flow velocity ratios. For submerged jets, experiments were also conducted at varying water depth but kept the velocity ratio constant. The differential temperature between the heated jet and the ambient water was about 20 F. Temperature, velocity and turbulence measurements were made. The predicted average temperatures are generally lower than the experimental values.
