The nowed forming of fluid and analysis:
The nowed forming of fluid is divided into two kinds of grown forms of laminar flow and turbulent flow (turbulent flow).
Laminar flow: fluid layering flows, and only makees to slide relatively between adjacent two layers fluid, lateral between fluid layer to mix.
Turbulent flow: when fluid flow rate is more than a certain numerical value, fluid no longer keeps laminar flow, and may transport to all directions
It is dynamic, have the component velocity perpendicular to tube axial direction, each fluid layer will be got mixed up, and be possible to be vortexed, this flow regime
Turbulent flow.
Fluid is in laminar flow or turbulence state is generally determined with Reynolds number.Reynolds number is small, it is meant that fluid each matter when flowing
In the highest flight, each particle of fluid is parallel to pipeline inner wall and flows regularly viscous force between point, is in laminar flow state.Thunder
Promise number is big, it is meant that in the highest flight, fluid is in Turbulence Flow state to inertia force, and general pipeline reynolds number Re < 2000 is laminar flow
State, Re > 4000 are turbulent condition, and Re=2000~4000 are transition state.Under different flow regimes, the fortune of fluid
The distribution etc. of dynamic rule flow velocity is all different, thus the mean flow rate of fluids within pipes and the ratio of maximum flow rate are also not
With.Therefore the size of Reynolds number determines the flow behavior of viscous fluid.
The calculation formula of Reynolds number:
Re=ρ vL/ μ
In formula:
Re is Reynolds number；ρ is fluid density；μ is fluid viscosity；V is the characteristic velocity in flow field；L is that the feature in flow field is long
Degree.
The beneficial effects of adopting the technical scheme are that
Turbulent flow is since fluid flow rate is fast, and it is larger to contain kinetic energy, makes the moving particle of internal fluid not only along pipe axis
The linear motion in direction mixes with one another between particle also with lateral disturbance, the flow regime of vortex phenomenon occurs.The present apparatus
To the fluid for being in turbulence state, by taking energy dissipating, damping, the measure for forcing water conservancy diversion, restrict shortest apart from interior as layer
Stream mode.

Setting.For fluid when by the inner cavity of rectangular tube, each damping fin generates damping energy dissipation effect to fluid, in rectangular tube
The fluid of chamber uniformly carries out energy consumption on the whole, avoids fluid flow state due to local resistance excessive generation line phenomenon
Generate interference.
The cavity length of rectangular tube is the three times of its height or more, meets fluid by turbulent flow and switchs to laminar flow to duct length
It is required that.
On the upper end edge and rectangular tube of each downward water conservancy diversion damping fin cavity wall connect, the left end edge of each downward water conservancy diversion damping fin and
Right end edge is connect with the left side wall top of rectangular tube and right side wall top respectively；The lower end edge and rectangle of each upward water conservancy diversion damping fin
Manage lower cavity wall connection, the left end edge of each upward water conservancy diversion damping fin and right end along respectively with the left side wall lower part of rectangular tube and right side wall
Lower part connection；The lower end edge of each downward water conservancy diversion damping fin and the inner cavity lower part of rectangular tube form and are forced up flow-guiding mouth, each upward
The upper end edge of water conservancy diversion damping fin and the inner cavity top of rectangular tube form and are forced downwardly flow-guiding mouth.Make fluid in rectangle tube cavity in S
The flowing of type longest path, in the case where rectangle length of tube is constant, farthest extends the flow distance of fluid, it may be assumed that increases
The characteristic length L in flow field is added.
The fluid of the height value of the width value > rectangular tube intracavity section of rectangular tube intracavity section, same volume is entering square
After shape tube cavity, thickness is opposite to be reduced, and the unordered fluid ability enhancing of each particle of internal fluid is restricted, to increase Reynolds number
Re is switched to the critical value of turbulent flow by laminar flow.
