WebEquations 4.2-3 and 4.2-4 are called Reynolds-averaged Navier-Stokes (RANS) equations. They have the same general form as the instantaneous Navier-Stokes … WebThe incompressible Navier–Stokes equations with conservative external field is the fundamental equation of hydraulics. The domain for these equations is commonly a 3 or less dimensional Euclidean space , for which an orthogonal coordinate reference frame is usually set to explicit the system of scalar partial differential equations to be solved.
