The decline flow velocity of tide pump depends primarily on tide flow velocity, Relatively density contrast.The device is using roly-poly type
Structure enables bent tube section to remain horizontal, on device to guarantee always to have a tide pump decline flow tube can be upright always
Solid dowel pin 8 be used to reduce the contact area of wedge bracket and seashore, prevent the ground of entire wedge bracket from contacting with seashore, to subtract
Less to benthic injury, the effect of the deflector of pipe bent position is the direction for making pumping hole always towards stream.
Feasibility in theory verifying:
If Fig. 3 is the Physical Mechanism schematic diagram that tide pumps, when the elbow inlet that stream is pumped by tide, since obstruction is imitated
It answers, horizontal flow velocity decline.According to bernoulli principle, this slow down will increase the static pressure of inlet, will overcome point if sufficiently large
Layer drives the sinking in tide pump.When not considering the detailed construction in flow field, law of conservation of energy (formula (1)) is in turbulent flow
It is used widely in the project analysis of pipe stream.The kinetic energy of level stream is sufficiently large to guarantee continuous sinking, wherein molecule
Viscosity and eddy flow consume the remaining kinetic energy of sinking.
max(hk-hρ, 0) and=hf (1)
Wherein, hkIt is kinetic head, hρIt is density contrast head, hfIt is the loss of fluid motion head.
The sinking ability of pump can be studied from the physical model of pump by the principle of similitude, thus reduce experimental period and
Expense, similitude are based on the control dynamic characteristic dimensionless number in flow field, including geometric similarity and two kinds of dynamic similarity.Geometry phase
It requires like property with all dimensions involved in common scaling prototype, not occur in the conversion of prototype to model
The deformation of flow structure.Scaled size includes pipe diameter D, pipe range L, radius of curvature R, mean water level h0, depth of pycnocline h0-h2
And pump is in spring layer immersion length h below1。
Wherein, subscript m and p respectively refer to model and prototype, and r refers to the ratio from model to prototype, h2It is intensive bottom water
Characteristic length, DrIt is designed as 80:1, it is contemplated that the limitation of the depth of water in experiment.
In artificial sinking, separation resistance and inertia force account for leading, and remaining force is relatively small.The ratio of both main forces
Value is nondimensional Richardson number, shows the dynamic importance of bottom horizontal flow sheet condition lower leaf.
Wherein, Ri is nondimensional Richardson number, and U is the flow velocity of level stream,It is the relative density difference in fluid
Ratio, g is acceleration of gravity, and H is spring layer immersion length below.Ri can be expressed as the ratio between density contrast head and kinetic head
Half, dynamic similarity can be by realizing the value is with model and prototype equal.
Wherein, vhIt is the horizontal flow velocity of upper curved inlet, ρiAnd ρoIt is the density of the water of spring layer above and below respectively.
All variables in relation to sinking essential characteristic can be mutually converted between model and prototype, for example, in prototype under
Flow Q dropsdIt is by being realized in a model with following coefficient multiplied by model.
By the comparison with experimental result shown in Fig. 4, the correctness of theoretical model is demonstrated, independent variable is nondimensional
Richardson number Ri, dependent variable are the kinetic head of sinking and the ratio of incident kinetic head, indicate the relative intensity of sinking.
Relationship between the two variables can pass throughIt is written equation (6).
Wherein, ξtIt is related total losses coefficient with the geometry of Reynolds number and pump, it is several by Reynolds number effect very little
Constant is a constant 1.33.Due to similitude, this relationship in prototype should follow scale model.Experimental result and reason
By coincideing substantially, there is minus deviation in principle, confirms the validity of tide pump model prediction sinking in practice.
