Abstract
PurposeThis 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.Design/methodology/approachThe 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.FindingsThe 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.Research limitations/implicationsNo solutions were found for α<4.16.Originality/valueThe study provides an application of the use of cybernetic methodology to a practical problem.
