Summary on Grant Application Form |
|
Strong turbulence can strongly distort a free surface, produce drops and bubbles and cause splashing. There is almost no previous quantitative study of this phenomena. Two papers by Brocchini and Peregrine provide a framework, the first for quantifying these flows, and the second setting out a basis for mathematical modelling.In this project turbulent flows will be studied by introducing obstacles into a stream in a laboratory flume. A range of flows will be explored, from those that onlyslightly disturb the surface through strongly disturbed surfaces, bubble and drop formation, to splashing flows. Simultaneous measurements will be made of the turbulence (with existing fibre optic LDV equipment), and of the motion of the free surface.On the theoretical side, various numerical models for water waves will be adapted to include turbulent flow regions. Mathematical approaches will range from the use of averaged large-scale parameters to more detailed models based on the averaged equations. At each step we will refer to dedicated experimental observations. Several aspects are likely to provide computational challenges, especially the major source of turbulence at the foot of a breaker.
