On the Frequency of Internal Gravity Waves in the Atmosphere: Comparing Theory with Observations
AtmosphereThis paper is devoted to the dynamics of the propagation of non-planetary scale internal gravity waves (IGWs) in the stratified atmosphere. We consider the system of equations describing internal gravity waves in three approximations: (1) the ...

Covariant fluid dynamics: a long wavelength approximation [PDF]
Classical and Quantum Gravity, 2003 In this paper we consider the Long-Wavelength Approximation Scheme (LWAS) in the framework of the covariant fluid approach to general relativistic dynamics, specializing to the particular case of irrotational dust matter. We discuss the dynamics of these models during the approach to any spacelike singularity where a BKL-type evolution is expected ...

Rational approximations of fluid properties
Fluid Phase Equilibria, 1993 Abstract We report on recent efforts to develop a systematic method, based on the technique of rational approximation, for creating mathematical models of real-fluid equations of state and related properties. Equation-of-state models for real fluids are usually created by selecting a function p ∗ (T,n) that contains a set of parameters &{;γ i ...

Higher-Order Models for Resonant Viscosity and Mass-Density Sensors
Sensors, 2020 Advanced fluid models relating viscosity and density to resonance frequency and quality factor of vibrating structures immersed in fluids are presented. The numerous established models which are ultimately all based on the same approximation are refined,

Entropy optimized flow of Jeffrey fluid with radiation effect over a stretched surface
Advances in Mechanical Engineering, 2022 The theme of this paper is to scrutinize hydromagnetic flow of Jeffrey fluid subject to stretched curved sheet. Heat expression is developed through dissipation, magnetic force and radiation. Entropy generation is also studied.

Two-Level Finite Element Approximation for Oseen Viscoelastic Fluid Flow
Mathematics, 2018 In this paper, a two-level finite element method for Oseen viscoelastic fluid flow obeying an Oldroyd-B type constitutive law is presented. With the newly proposed algorithm, solving a large system of the constitutive equations will not be much more ...

Multilayer approximation for a confined fluid in a slit pore [PDF]
Papers in Physics, 2010 A simple Lennard-Jones fluid confined in a slit nanopore with hard walls is studied on the basis of a multilayer structured model. Each layer is homogeneous and parallel to the walls of the pore.

A fluid approximation for large-scale service systems [PDF]
ACM SIGMETRICS Performance Evaluation Review, 2010 We introduce and analyze a deterministic fluid model that serves as an approximation for the Gt/GI/st + GI manyserver queueing model, which has a general time-varying arrival process (the Gt), a general service-time distribution (the first GI), a time-dependent number of servers (the st) and allows abandonment from queue according to a general ...

Wave Instabilities of a Collisionless Plasma in Fluid Approximation [PDF]
Contributions to Plasma Physics, 2010 AbstractWave properties and instabilities in a magnetized, anisotropic, collisionless, rarefied hot plasma in fluid approx‐imation are studied, using the 16‐moments set of the transport equations obtained from the Vlasov equations. These equations differ from the CGL‐MHD fluid model (single fluid equations by Chew, Goldberger, and Low [5,9]) by ...
