Short term dynamics of a free falling jet due to solitonic collision
Résumé
The impact of two steep solitonic waves propagating in counter directions leads to the formation of a free fall residual jet. We investigate numerically and theoretically the characteristics of this jet, including the criteria of formation, and the short term dynamics. The numerical approach is based on a boundary integral elements method, allowing to compute the pressure of the inner flow. A theoretical description based on potential flow theory is introduced to describe the short term evolution of the jet.
