The paper studies the geometrical aspects of steady, two-dimensional potential flows and their relation to the physics that governs them. To achieve this, the streamline curvature of a flow is determined when the vector velocity field describing it, is known. Two methods, which allow the calculation of streamline curvature at every point of a flow field, are developed: the 'Method of Rotation' and the 'Method of Directional Derivative'. Especially the first method reveals an interesting feature of curvature, allowing it to be interpreted kinematically. Furthermore, an attempt has been made towards the formulation of a potential theory from a geometrical perspective. For this reason the concept of 'Global Curvature' is introduced, being a measure of both stream and potential line curvature. It has been proven that it contains all the information needed to determine the physical quantities of velocity and static pressure throughout a potential flow, thus depicting the strong link between geometry and physics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
