Abstract
A theoretical model of axisymmetric turbulent fountains in both homogeneous and
stratified fluids is developed. The model quantifies the entrainment of ambient fluid
into the initial fountain upflow, and the entrainment of fluid from both the upflow
and environment into the subsequently formed downflow. Four different variations
of the model are considered, comprising the two most reasonable formulations of
the body forces acting on the ‘double’ structure and two formulations of the rate of
entrainment between the flows. The four model variations are tested by comparing
the predictions from each of them with experimental measurements of fountains in
homogeneous and stratified fluids.
