Abstract
The invention provides a telescopic nanofluid fuel combustion characteristic testing device. The device comprises a pipe body, and a groove body positioned in the pipe body and moving in the axial direction of the pipe body, wherein the groove body is formed by cutting the pipe body in a direction parallel to the axis; and when the front end of the groove body moves to the outer side of a port of a combustion end of the pipe body, a fluid is burnt on an opening section, parallel to the axis of the pipe body, of the groove body out of the pipe body. The nanofluid can form more stable flame through the device; and combustion solid residues are easy to collect and sample.
Description
Technical field
The present invention relates to a kind of fluent material combustion technology, a kind of telescopic nano-fluid fuel combustion characteristics test device.
Background technology
Nano-fluid refers to the novel heat exchange medium of the heat conduction uniform, stable, high that certain mode and ratio add nano level metal in a liquid or metal oxide particle is prepared as, there is low ignition point, high fuel value, the advantage of low stain thing discharge, receive the extensive concern of domestic and international researcher.But, the combustion mechanism of nano-fluid fuel is not perfect, and the process therefore probing into nano-fluid fuel combustion from basic angle has important theory significance and practical value.The method being generally used for the research of nano-fluid fuel combustion characteristics cannot test nano-fluid fuel continuous burning process for single droplet burning test, the method, and should be continuous burning in nano-fluid fuel actual application, rather than simple individual particle droplet burning.
Oxidation reaction is easily there is in the nanoparticle being suspended in nano-fluid in nano-fluid fuel combustion process, collect and analyze the chemical change that the solid residue of burning occurred for analyzing nanoparticle in nano-fluid fuel combustion process and there is important effect, simultaneously facilitate nanoparticle and the synergistic research of substrate fuel.Nano-fluid fuel is passed through common quartz glass straight tube and lights in exit, then in 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 lights in exit, then burning solid residue is scattered in end face, is difficult to concentrate, it is more difficult to collecting and sampling.
Summary 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 can form relatively stable flame by this device, and the sampling of burning solid fraction collection is easily.
A kind of telescopic nano-fluid fuel combustion characteristics test device, including body and the cell body that in being placed in body and moves axially along body；Wherein cell body is formed along the direction cutting being parallel to axis by a body, and when cell body front end is moved to body fire end port, fluid is parallel at the opening section of body axis burn in the cell body outside body.
The present invention is compared with prior art, have the advantage that (1) present invention movement by cell body, the area respective change of its port, be adapted to the fluid of different in flow rate to reach the effect of stable burning, by the physical measurement of flame, the performance of estimation nano-fluid fuel；(2) after burned, burning solid residue is gathered in half opening cambered surface, this burning solid residue is collected sampling easily.
Below in conjunction with Figure of description, the present invention is described further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the generalized section of the present invention.
Fig. 3 is fluid combustion schematic diagram of the present invention, and the time interval of two wherein the most adjacent in (a) to (h) width figures is 2ms.
Detailed description of the invention
In conjunction with Fig. 1, a kind of telescopic nano-fluid fuel combustion characteristics test device, including body 1 and the cell body 2 that in being placed in body 1 and moves axially along body 1.Wherein cell body 2 is formed along the direction cutting being parallel to axis by a body, and when cell body 2 front end is moved to body 1 fire end port, fluid is parallel at the opening section of body 1 axis burn in the cell body 2 outside body 1.Dotted line in Fig. 1 is cell body 2 structure within body 1.
Owing to cell body 2 exposes at body 1 outside bigger than the area of existing body fire end, adding the contact area of fluid fuel and air, and fluid during burning can be played a supporting role by wall, therefore flame can stably burn.Through experiment, described cell body 2 is formed by a body can obtain the most stable flame along axis cutting.
In conjunction with Fig. 2, body 1 inwall arranges a rectilinear orbit groove in the axial direction, and cell body 2 outer wall is provided with the track key 3 mated with this rail groove.Two end faces of described rail groove non-UNICOM body 1.Between cell body 2 and body 1, between matched in clearance or cell body 2 and body 1, sealing ring 4 is set.
In conjunction with Fig. 3, for when flow is 0.5ml/min, when adding the 100nm aluminum particulate nano-fluid with ethanol as substrate that concentration is 1.0%, this invention device burns, can observe its flameholding, the time interval of two wherein the most adjacent in (a) to (f) width figures is 2ms.
