Numerical simulation of high-swirl flow in axial turbine stage

open access: yesEPJ Web of Conferences, 2016
This article deals with numerical modelling of flow in an axial turbine stage with prismatic blades which are not equipped with shroud. In this case flow through a radial gap above and below ends of blades leads to generation of strong secondary vortices

Couette-Hiemenz exact solutions for the steady creeping convective flow of a viscous incompressible fluid with allowance made for heat recovery

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2018
In this paper, we study the steady creeping convective flow of a viscous incompressible fluid in the thin infinite layer. The study of the fluid flow is based on the exact solutions class for the Oberbeck-Boussinesq equations in the Stokes approximation ...

A Karhunen-Loève based Galerkin approximation to Boussinesq equation

open access: yes, 1996
The Boussinesq equation which is derived from the Navier-Stokes equation is approximated by the amplitude equations constructed through the Karhunen-Loeve (K-L) based Galerkin projection.

Spectral Jacobi approximations for Boussinesq systems

open access: yesStudies in Applied Mathematics
AbstractThis paper is concerned with the numerical approximation of initial‐boundary‐value problems of a three‐parameter family of Bona–Smith systems, derived as a model for the propagation of surface waves under a physical Boussinesq regime. The work proposed here is focused on the corresponding problem with Dirichlet boundary conditions and its ...

Thermal convection and the Boussinesq approximation for ideal gases in the light of kinetic theory

open access: yes
A systematic asymptotic analysis of the Boltzmann equation for monatomic ideal gases is carried out under the conditions that the mean free path of gas molecules and the external force are both small, and the results are compared with the Boussinesq ...

Boussinesq approximation of the Cahn-Hilliard-Navier-Stokes equations [PDF]

open access: yes, 2010
We use the Cahn-Hilliard approach to model the slow dissolution dynamics of binary mixtures. An important peculiarity of the Cahn-Hilliard-Navier-Stokes equations is the necessity to use the full continuity equation even for a binary mixture of two ...

Weakly Nonlinear Instability of a Convective Flow in a Plane Vertical Channel

open access: yesFluids
The weakly nonlinear stability analysis of a convective flow in a planar vertical fluid layer is performed in this paper. The base flow in the vertical direction is generated by internal heat sources distributed within the fluid.

Energy Stability of Benard-Darcy Two-Component Convection of Maxwell Fluid

open access: yesInternational Journal of Applied Mechanics and Engineering, 2013
Energy stability of a horizontal layer of a two-component Maxwell fluid in a porous medium heated and salted from below is studied under the Oberbeck-Boussinesq-Darcy approximation using the Lyapunov direct method.

The approximate solutions of nonlinear Boussinesq equation

open access: yesJournal of Physics: Conference Series, 2016
The homotopy analysis method (HAM) is introduced to solve the generalized Boussinesq equation. In this work, we establish the new analytical solution of the exponential function form. Applying the homotopy perturbation method to solve the variable coefficient Boussinesq equation.
