WebMay 7, 2024 · A direction splitting scheme for Navier-Stokes-Boussinesq system in spherical shell geometries. This paper introduces a formally second-order direction … WebWe introduce a hybrid Galerkin modelling tool for the nonlinear acoustic and gravity wave propagation in planetary atmospheres coupled through topography to a solid medium. We rely on a 2-D spectral-element technique to model linear visco-elastic solid media and couple it to a discontinuous Galerkin method for the atmosphere modelled by the fully nonlinear …

WebAbstract: We prove the global existence of weak solutions to the Cauchy problem for the compressible isentropic Navier–Stokes equations in ℝ n ( n = 2, 3) when the Cauchy data … The Navier–Stokes momentum equation can be derived as a particular form of the Cauchy momentum equation, whose general convective form is where $${\textstyle {\frac {\mathrm {D} }{\mathrm {D} t}}}$$ is the material derivative, defined as $${\textstyle {\frac {\partial }{\partial t}}+\mathbf {u} \cdot \nabla … See more The Navier–Stokes equations are partial differential equations which describe the motion of viscous fluid substances, named after French engineer and physicist Claude-Louis Navier and Anglo-Irish physicist and … See more The solution of the equations is a flow velocity. It is a vector field—to every point in a fluid, at any moment in a time interval, it gives a vector whose direction and magnitude are those … See more The incompressible momentum Navier–Stokes equation results from the following assumptions on the Cauchy stress tensor: See more Taking the curl of the incompressible Navier–Stokes equation results in the elimination of pressure. This is especially easy to see if 2D Cartesian flow is assumed (like in the … See more Remark: here, the deviatoric stress tensor is denoted $${\textstyle {\boldsymbol {\sigma }}}$$ (instead of $${\textstyle {\boldsymbol {\tau }}}$$ as it was in the general continuum equations and in the incompressible flow section). The compressible … See more The Navier–Stokes equations are strictly a statement of the balance of momentum. To fully describe fluid flow, more information is … See more Nonlinearity The Navier–Stokes equations are nonlinear partial differential equations in the general case and so remain in almost every real situation. In some cases, such as one-dimensional flow and Stokes flow (or creeping flow), the … See more WebIncompressible Form of the Navier-Stokes Equations in Spherical Coordinates The conservation of momentum equations.
