WebThe Navier–Stokes equations can be simplified to yield the Euler equations for describing inviscid flows. Together with the mass conservation equation, the Navier–Stokes equations allow the describing of internal and external flow problems in which due account of the equilibrium of the fluid in motion is made under isothermal conditions. WebThese are the Navier-Stokes equations and Euler’s equations. Navier-Stokes Equations. Fluid dynamics discussions generally start with the Navier-Stokes equations, ... such a case is related to the treatment of non-Newtonian fluids. We also have a thermodynamic equation describing the flow: Enthalpy portion of the Navier-Stokes …
WebNavier-Stokes Background. On the most basic level, laminar (or time-averaged turbulent) fluid behavior is described by a set of fundamental equations. These equations are: The Navier-Stokes equation is obtained by combining the fluid kinematics and constitutive relation into the fluid equation of motion, and eliminating the parameters D and T.
