Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is the structural representation of the water tank bottom flowing water aperture of the present invention；
Fig. 3 is the projection structure schematic diagram inside the projector of the present invention.
Embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describe in detail the present invention embodiment.As shown in figure 1, a kind of stream
Body demonstrating experiment device includes：The device includes water tank 1, demonstration box 5, support 9, the projector 7 of adjustable background luminance, dyestuff leakage
Bucket 14, discharge dyestuff flexible pipe 12, water supply hose 3, scupper hose 8 etc..
The bottom of demonstration box 5 is organic clear glass 17, is provided with water tank 1 in the end of demonstration box 5, the bottom of water tank 1 is provided with
Away from color nozzle water pipe 2, be connected by discharging dyestuff flexible pipe 12 with dyestuff funnel 14, discharge dyestuff flexible pipe 12 on be provided with
Adjusting knob 11, the flow velocity of the dyestuff water 13 of the outflow of color nozzle water pipe 2 can be controlled by adjusting knob 11.Dyestuff water 13 is most
Discharged eventually by scupper hose 8 out of demonstration box 5.
As depicted in figs. 1 and 2, tap is directly connected to water supply hose 3, and water tank 1, water tank 1 are connected to by water supply hose 3
The water that bottom is provided with equidistant flowing water aperture 16, water tank 1 uniformly flows into demonstration box 5 by flowing water aperture 13.Water is adjusted
Section knob 4 can control the water level in water tank 1, and water tank upper is provided with spout hole 10, it is to avoid occur the phenomenon that water overflows.Water
The water of outflow is discharged eventually through scupper hose 8 out of demonstration box 5 in case 1.
Selected dyestuff water 13 should make that the diffusion of dyeing line is slow, stability is good, can choose ink, potassium permanganate and aniline
Alcoholic solution of pigment etc., color and the flow field background of dyestuff water form strong contrast, are easy to observation.
It is put into after the experiment module of different shapes of detection, is adjusted not by adjusting knob 11 inside demonstration box 5
Same flow velocity, intuitively can significantly observe that dyeing line flowing flows to the evolution of turbulent flow from laminar flow to transition, fluid
Flow regime can be quantified with Reynolds number.From hydrodynamics, by adjusting knob 11 color nozzle water pipe 2 is flowed out
During the dyeing line flow velocity very little of the formation of dyestuff water 13, Reynolds number is smaller, and the influence of viscous force stream field is more than in inertia force, flow field
The disturbance of flow velocity can decay because of viscous force, and flowing is stable, and the laminar flow from dye nozzles water pipe 2 of dyestuff water 13 is not mixed mutually
Close, be laminar flow；Flow velocity is gradually increased by adjusting knob 11, Reynolds number is consequently increased, the dyeing line of fluid starts ripple occur
The swing of wave-like, the frequency and amplitude of swing increase with the increase of flow velocity, to cross stream；When flow velocity increases to it is very big when, Reynolds
Coefficient is larger, and the influence of inertia force stream field is more than viscous force, and dyeing line flows more unstable, the small change of the flow velocity of dyestuff water 13
Change easily development, enhancing, dyeing line is no longer clear variable, there are many small whirlpools in flow field, forms disorderly, irregular turbulent flow
.
As shown in figure 1, being placed with the experiment module of different shapes of detection inside demonstration box 5, demonstration box 5 is in projector
7 tops, the bottom of demonstration box 5 is lucite 17, and projector 7 provides bias light for the lucite 17 of demonstration box 5, can adjust bright
The dyestuff water 13 that dye nozzles water pipe 2 inside degree, demonstration box 5 flows out is projected to CCD in the streamline that the inside of demonstration box 5 is produced
On sensor 13.Computer is transferred data to by CCD, and by means of the processing means of computer, it would be desirable to data it is real
When show and by means of the software processing means of computer, image and data can in real time be shown, and carry out corresponding
Data analysis and analog image reconstruct.
As shown in figure 3, projector 7 includes light source 6, lucite 17, lateral reflector 18, bottom mirror 19, it is former
Reason is light that is that light source 6 is sent and being reflected by lateral reflector 18, is further reflected by bottom mirror 19, last vertical
It is radiated on lucite 17, forms the background of brightness uniformity, its background luminance can adjust.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
