Abstract
The present invention provides a kind of telescopic nano-fluid fuel combustion characteristics test device, including body and the cell body that is placed in body and is moved axially along body；Wherein cell body is cut along the direction parallel to axis by a body and formed, and when cell body front end is moved on the outside of body fire end port, cell body of the fluid outside body burns parallel at the opening section of body axis.Nano-fluid can form relatively stable flame by the device, and the sampling of burning solid fraction collection is easy.
Description
Technical field
The present invention relates to a kind of fluent material combustion technology, particularly a kind of telescopic nano-fluid fuel combustion characteristics are surveyed
Trial assembly is put.
Background technology
Nano-fluid refers to that certain mode and ratio add nano level metal or metal oxide particle system in a liquid
It is standby into it is uniform, stably, the novel heat exchange medium of high heat conduction, there is the advantages of low ignition point, high fuel value, discharge of low stain thing,
Receive the extensive concern of domestic and international researcher.However, the combustion mechanism of nano-fluid fuel is not perfect, therefore from basic angle
Spending the process for probing into nano-fluid fuel combustion has important theory significance and practical value.It is generally used for nano-fluid fuel
The method of combustion characteristics research is tested for single droplet burning, and this method can not test nano-fluid fuel continuous burning process, and
Continuous burning, rather than simple individual particle droplet burning are should be in nano-fluid fuel actual application.
It is suspended in the nano-particle in nano-fluid and oxidation reaction easily occurs in nano-fluid fuel combustion process, collects
And the chemistry that the solid residue for analyzing burning is occurred for analysis nano-particle in nano-fluid fuel combustion process becomes
Change has the function that research that is important, while promoting nano-particle to be acted synergistically with substrate fuel.Nano-fluid fuel is passed through general
Logical quartz glass straight tube is simultaneously lighted in exit, then burning solid residue is gathered in pipe, it is more difficult to collecting and sampling.Nano-fluid
Fuel is passed through electric arc and jet-burner and lighted in exit, then burning solid residue is scattered in end face, is not easy to concentrate, compared with
Difficult collecting and sampling.
The content of the invention
It is an object of the invention to provide a kind of telescopic nano-fluid fuel combustion characteristics test device, nano-fluid leads to
Relatively stable flame can be formed by crossing the device, and the sampling of burning solid fraction collection is easy.
A kind of telescopic nano-fluid fuel combustion characteristics test device, including body and be placed in body and along body axle
To mobile cell body；Wherein cell body is cut along the direction parallel to axis by a body and formed, when cell body front end is moved to body
On the outside of fire end port, cell body of the fluid outside body burns parallel at the opening section of body axis.
The present invention compared with prior art, has advantages below：(1) movement of the invention by cell body, its port
Area respective change, fluid different in flow rate is adapted to reach the effect of stable burning, passes through the physical measurement of flame, estimation
The performance of nano-fluid fuel；(2) after burned, burning solid residue is gathered in half opening cambered surface, residual to this burning solid
Thing is stayed to be collected sampling easy.
The present invention is described further with reference to Figure of description.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the diagrammatic cross-section of the present invention.
Fig. 3 is fluid combustion schematic diagram of the present invention, wherein the time interval in (a) to (h) per two adjacent width figures is
2ms。
Embodiment
With reference to Fig. 1, a kind of telescopic nano-fluid fuel combustion characteristics test device, including body 1 and be placed in body 1
And the cell body 2 moved axially along body 1.Wherein cell body 2 is cut along the direction parallel to axis by a body and formed, when cell body 2
Front end is moved on the outside of the fire end port of body 1, opening section of cell body 2 of the fluid outside body 1 parallel to the axis of body 1
Place's burning.Dotted line in Fig. 1 is the structure of cell body 2 inside body 1.
The area exposed due to cell body 2 at the outside of body 1 than existing body fire end is big, adds fluid fuel and air
Contact area, and wall can to burning when fluid play a supporting role, therefore flame can stablize burn.By reality
Test, the cell body 2 is cut to be formed by a body along axis can obtain flame the most stable.
With reference to Fig. 2, the inwall of body 1 sets a rectilinear orbit groove in the axial direction, and the outer wall of cell body 2 is provided with and the rail groove
The track key 3 of matching.Two end faces of the non-UNICOM's body 1 of rail groove.Gap cooperation or cell body 2 between cell body 2 and body 1
Sealing ring 4 is set between body 1.
With reference to Fig. 3, for when flow is 0.5ml/min, addition concentration is 1.0% 100nm aluminum particulates and with ethanol
For substrate nano-fluid when, burnt in the invention device, its flameholding can be observed, wherein per phase in (a) to (f)
The time interval of two adjacent width figures is 2ms.
