Abstract | It has been shown that a wide class of 3D motions of incompressible viscous fluid in Cartesian coordinates can be described by only one scalar function dubbed the quasi-potential. This class of fluid flows is haracterized by three-component velocity field having two-component vorticity field; both these fields can depend of all three spatial variables and time, in general. Governing equations for the quasi-potential have been derived and simple illustrative examples of 3D flows have been presented. In this paper the concept of quasi-potential is further developed for fluid flows in cylindrical coordinates. It is shown that the introduction of a quasi-potential in curvilinear |
