Nettet21. aug. 2024 · Three possible integral forms of the equations of motion are presented. As a conclusion, the existence and smoothness of the solution of the Navier-Stokes equations are considered. Keywords: continuity equation, Navier-Stokes equation, Bernoulli equation, existence and smoothens of the solutions of Navier-Stokes … Nettet23. jun. 2010 · Accordingly, in this paper, a first integral of the Navier–Stokes equations for steady flow is constructed. In the case of a two-dimensional flow, this is made possible by formulating the governing equations in terms of complex variables and introducing a new scalar potential. rtbf psg real
