Stability of steady-state non-Newtonian fluid layer flow
Springer Science and Business Media LLC - Tập 47 Số 6 - Trang 694-701 - 2012
Nonstationary secondary flows in spherical layers
Springer Science and Business Media LLC - Tập 33 - Trang 463-465 - 1998
An experimental study of the change in secondary flow type at the main flow stability limit is presented. For spheres rotating in the same direction, it is found that the passage from the main flow to a three-dimensional secondary flow occurs via a nonstationary transition regime. The paper continues the study [1] in which the three-dimensional stability limit of the main flow in the space of the ......

Supersonic nonuniform viscous gas flow past a blunt body with supply of gas from the surface
Springer Science and Business Media LLC - Tập 23 - Trang 585-591 - 1988
The problem of axisymmetric nonuniform gas flow past smooth blunt bodies at high Mach numbers is investigated. The approach stream is a parallel axisymmetric flow in which the velocity and temperature depend on the radial distance from the axis of symmetry and the pressure is constant. On the axis of symmetry the velocity has a minimum and the temperature a maximum. A characteristic feature of thi......
Relaxation, propagation of sound, and transfer processes in molecular gases
Springer Science and Business Media LLC - Tập 5 - Trang 758-769 - 1970
Taking account of rotational and vibrational degrees of freedom of the molecules, a system of equations has been obtained for a molecular gas which describes slightly nonequilibrium states with a length and time on the order of magnitude of the length and time of the rotational and vibrational relaxation. By solving this system, which describes the propagation of sound and the transfer process, th......
Method of Selective Injection of Chemical Reactants into a Inhomogeneous Layered Reservoir
Springer Science and Business Media LLC - Tập 36 - Trang 971-976 - 2001
The unsteady process of homogeneous compressible fluid flow through a porous weakly deformable inhomogeneous layered reservoir is considered in the absence of a hydrodynamic connection between the layers. A method of selective injection of chemical reactants into high- or low-permeability parts of the reservoir based on fluid injection at a rate determined by the intensity of the well-bore crossfl......
On the propagation of pressure waves in saturated porous media
Springer Science and Business Media LLC - Tập 31 - Trang 865-867 - 1996
The problem of the propagation of pressure waves through compressible porous media saturated with a slightly compressible fluid is considered. By using Darcy's law the problem is reduced to a mixed initial-boundary value problem for an equation of the heat conduction type with a nonlinear term. The method of quasi-characteristics is used to solve this equation numerically. Solutions of the wave pr......
Self-similar solutions describing the propagation of solitary waves above underwater ridges and troughs
Springer Science and Business Media LLC - - 1985
The nonlinear ray method [1] is used to investigate the propagation of solitary waves over an uneven bottom. In the process of nonlinear evolution of the wave front, singular points develop in it; these are treated in the given model as discontinuities [2, 3]. In contrast to earlier studies, it is not assumed here that the intensity of the discontinuity is weak. Boundary conditions at the disconti......
Exact Solution of the Heat Transfer Problem for a Rotating Disk under Uniform Jet Impingement
Springer Science and Business Media LLC - Tập 38 - Trang 18-27 - 2003
An exact solution of the heat transfer problem for a uniform air stream impinging on a rotating disk is found. By introducing self-similar radial velocity and temperature profiles, the problem is reduced to a system of ordinary differential equations which are solved numerically. The Nusselt numbers are calculated for Prandtl numbers equal to 1 and 0.71 and various ratios of the free-stream veloci......
Multicomponent diffusion of various admixtures in turbulent flow
Springer Science and Business Media LLC - Tập 25 - Trang 327-334 - 1990
Averaged equations describing the turbulent diffusion of a chemically active admixture in coordinates tied to the instantaneous values of the concentration of another passive admixture are obtained. The results can be readily extended to the case of an arbitrary number of different chemically active admixtures. An advantage of this approach is the separation of the scales of the fluctuating and av......
