New form of the equations of motion of a viscous fluid in Lagrangian variables
A. A. Abrashkin, E. I. Yakubovich Institute of Applied Physics, Russian Academy of Sciences, Nizhnii Novgorod, 603000
Abstract:
An equation is derived which describes the motion of an incompressible viscous fluid in Lagrangian variables. Velocity circulations over contours enclosing infinitesimal areas in each of the planes of the Lagrangian variables (Cauchy invariants) are taken to be unknown functions. Examples of exact solutions obtained using this method of flow description are analyzed.
Keywords:
viscosity, Cauchy invariants, vorticity, Lagrangian variables.
