Method of Computing Fluid Motion in Two-Dimensional Cartesian or Cylindrical Coordinates by Following Lagrangian Energy Cells
Abstract
It is conjectured that for some physical flow problems there may be an advantage in following energy exactly as one follows mass elements in the conventional Lagrangian formulation of fluid dynamics. Essentially, the argument is a generalization to two dimensions of an idea due to Enig who derived the equations for one-dimensional slab geometry. The equations are derived both differentially and integrally from the Eulerian form, and they are compared with the conventional Lagrangian equations.
