Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the structure diagram of the water tank bottom flowing water aperture of the utility model；
Fig. 3 is the projection structure schematic diagram inside the projector of the utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment of the present utility model is described in detail in preferred embodiment.As shown in Figure 1, one
Kind fluid demonstrating experiment device includes：The device includes water tank 1, demonstration box 5, stent 9, the projector 7 of adjustable background luminance, dye
Funnel 14, discharge dyestuff hose 12, water supply hose 3, scupper hose 8 etc..
5 bottom of demonstration box is organic transparent glass 17, is equipped with water tank 1 in 5 end of demonstration box, 1 bottom of water tank is provided with
Away from color nozzle water pipe 2, be connected by discharging dyestuff hose 12 with dyestuff funnel 14, discharge dyestuff hose 12 on be equipped with
Adjusting knob 11 can control the flow velocity of the dyestuff water 13 of the outflow of color nozzle water pipe 2 by adjusting knob 11.Dyestuff water 13 is most
The discharge out of demonstration box 5 by scupper hose 8 eventually.
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
Bottom is provided with equidistant flowing water aperture 16, and the water in water tank 1 passes through flowing water aperture 13 and uniformly flows into demonstration box 5.Water tune
Section knob 4 can control the water level in water tank 1, and water tank upper is provided with spout hole 10, avoid that the phenomenon that water overflows occurs.Water
The water of outflow discharge out of demonstration box 5 eventually by scupper hose 8 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, convenient for observation.
After the experiment module of different shapes of detection is put into inside demonstration box 5, adjusted not by adjusting knob 11
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, flowed out by 11 color nozzle water pipe 2 of adjusting knob
During the dyeing line flow velocity very little that dyestuff water 13 is formed, Reynolds number is smaller, and the influence of viscous force stream field is more than inertia force, in flow field
The disturbance of flow velocity can decay due to viscous force, and flowing is stablized, and the laminar flow from dye nozzles water pipe 2 of dyestuff water 13 is not mixed mutually
It closes, is laminar flow；Flow velocity is gradually increased by adjusting knob 11, Reynolds number is consequently increased, and 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 13 flow velocity of dyestuff water
Change easily development, enhancing, no longer clear variable, the small whirlpool in many of flow field of dyeing line 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, 5 bottom of demonstration box are organic glass 17, and projector 7 provides bias light for the organic glass 17 of demonstration box 5, can adjust bright
It spends, the dyestuff water 13 that the dye nozzles water pipe 2 inside demonstration box 5 flows out is projected to CCD in the streamline that 5 the inside of demonstration box generates
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 real-time display can be come out, and carried out corresponding
Data analysis and analog image reconstruct.
As shown in figure 3, projector 7 includes light source 6, organic glass 17, lateral reflector 18, bottom mirror 19, it is former
Reason is that light source 6 is sending and by the light that lateral reflector 18 reflects, and is further reflected by bottom mirror 19, last vertical
It is radiated on organic glass 17, forms the background of brightness uniformity, background luminance is adjusted.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
