This study aims to calculate 2D free surface potential flow of a liquid poured from a container when the liquid runs along the underside of the spout.
The effect of surface tension is taken into consideration and gravity is neglected. The solutions for the free‐surface profiles were computed numerically using a boundary‐integral equation.
The numerical computation shows that the solutions are found for different values of α and a train of capillary waves in the far field for 4.16≤α<10.
No solutions were found for α<4.16.
The study provides an application of the use of cybernetic methodology to a practical problem.
