Stability of the free-convection boundary layer on a vertical permeable plate

The hydrodynamic stability of flow in a free-convection boundary layer on a permeable plate is numerically investigated. The effect of the plate nonisothermicity and the injection blowing intensity on the critical parameters is determined.

Flow stability in a plane-parallel channel with one permeable wall

We have calculated the characteristics of neutral flow stability in a plane-parallel channel with injection or suction through a permeable wall.

Heat exchange in tubes with permeable walls in the presence of internal heat sources

Solutions are obtained for the energy equation for fluid flow in tubes with uniform injection of suction and heat sources in the stream.

Modeling nonlocal mass transfer of a dispersed impurity in turbulent flows of a gas suspension

The effect of nonlocal phenomena occurring with the motion of inertial particles on the rate of mass transfer of the dispersed phase is studied on the basis of a closed expression constructed for the probability density function determining the transport of these particles in a turbulent nonuniform flow.

Numerical and experimental modeling of turbulent flows in furnace chambers

Results are presented from an experimental and numerical modeling of two-dimensonal turbulent flows in furnace chambers. The article follows the evolution of the flow patterns with a change in the configuration of the chamber. The range of validity of the study results are discussed.

Thermohydraulic stability of helium flow at supercritical pressure under conditions of forced and mixed convection in a vertical heated channel

The excitation of thermally induced oscillations in low-temperature helium flow in channels with different orientation are studied and the boundaries of stability are constructed.

Flow and heat transfer of finely dispersed turbulent flows in channels

Equations for the second moments of the velocity and temperature fluctuations are used to study the effect of particles on the rate of turbulent momentum and heat transfer in the flow of a gas suspension in circular pipes.

Stability of a low-temperature helium flow in heated channels

The stability of a turbulent helium flow under forced convection is investigated in channels with different hydraulic characteristics.

INFLUENCE OF THERMOGRAVITATIONAL FORCES ON TURBULENT TRANSPORT FOR VARIOUS ORIENTATIONS OF THE FLOW AND THE SURFACE AROUND WHICH THE FLOW IS OCCURRING

On the basis of the second-moment balance equations, the influence of free convection on the intensity of turbulent transport in the boundary layer for various orientations of the flow and the surface around which the flow is occurring is studied.

Entrance section heat transfer in flow of helium at supercritical pressure

It is shown that heat transfer in the entrance section depends on the flow parameters (inlet pressure and temperature), distance from the inlet, and gas heating level.
