ALOIS, Alberto R  and  RINCON, Adriana F. YOUNG-LAPLACE EQUATION IN CONVENIENT POLAR COORDINATES AND ITS IMPLEMENTATION IN MATLAB®. Rev.Colomb.Quim. [online]. 2010, vol.39, n.3, pp.413-425. ISSN 0120-2804.

A new form of expression for the Young-Laplace equation is proposed. The Young-Laplace equation is developed in a convenient polar coordinate system and programmed in MatLab®. The profile generated showed to be in agreement with those reported in literature. An algorithm that avoids profile interpolation was developed and tested for the measurement of surface tension from profiles of pendant drops.

Keywords : drop profile; polar coordinates; Young-Laplace equation; MatLab®.
