The present paper briefly describes the principle of steel circulation flow during RH refining and discusses factors affecting the liquid steel compositions and temperature homogenization and finds out the measures concerned for temperature homogenization.
The experimental results of the forming of axial circular flow shows that axial circular flow can be realized in non-intermeshing, intermeshing co-rotating twin-screw extruders, but not in intermeshing counter-rotating twin-screw extruder.
Then the effect of introduction of axial circular flow on the transporting character and mixing capability of non-intermeshing, intermeshing co-rotating and counter-rotating twin-screw extruders is studied too.
The fluid flow is described in the frame of Eulerian-Lagrangian scheme. In order to account for the turbulent circulating flow induced by gas bubbling through the bottom, the κ-ε turbulence model is adopted in the fluid dynamics calculation, in which the fluctuation of the free surface of the melt is traced by means of a general-purpose FLOW-3D code.
Complex analysis of turbulence models, algorithms, and grid structures at the computation of recirculating flow in a cavity by m
A steady pressure gradient, parallel to the axis of the layer, drives a one-directional stationary non recirculating flow when the Darcy law has to include inertial and viscous corrections.
The flow-field features around the reentry capsule, such as bow shock wave, sonic line, expansion fan and recirculating flow in the base region are obtained.
0.5 to 10 and 15 to 25?μm particles were suspended in a recirculating flow tank filled with seawater, and ablated antennae were exposed to this flow, after which the captured particles were counted.
The complex fluid-dynamic aspects of a turbulent recirculating flow in a cavity with axial throughflow, and a rotating wall, were investigated by adopting a simple procedure for evaluating the turbulent stresses.
For all a, excluding a certain interval (α1, α2), the usual postcritical branching takes place: at a small supercriticality the circular flow loses stability and is "softly" excited into a secondary stationary flow - stable Taylor vortices.
We study the circular flow of a viscous incompressible liquid around a disc and a cylinder, in the range of Reynolds numbers 40 ≤ Re ≤ 1000.
Schumpeter's circular flow, learning by doing and cyclical growth
Thus we are able to show that learning mechanisms alone may be sufficient to destroy the circular flow as described by Schumpeter.
Analytical solution of conjugate heat transfer and optimum configurations of flat-plate heat exchangers with circular flow chann
With these hypotheses we can use the Prandtl-Batchelor theorem , which states that, in the limit as Re → ∞, a region of circulating flow becomes vortex flow of an inviscid liquid with constant vorticity ω.
The contribution of the self-excited thermal circulation of the gas to the total circulating flow is analyzed.
This periodic structure consists of volumes with a closed circulating flow alternating with "open" volumes hydrodynamically communicating with each other and the end of the pipe through wall flow zones.
The problem of the circulating flow of a nonisothermal magnetic fluid in a long vertical cylinder placed in a rotating magnetic field is solved in the weak vorticity approximation.
This involves the complex interaction between the external flow and the re-circulating flow within the cavity.
