Abstract
The invention discloses a boundary layer temperature measurement method, which comprises the following steps of: (1) arranging a temperature measurement probe at a position to be tested in a boundary layer temperature field, sequentially connecting a thermocouple with a data acquirer and a computer, debugging the thermocouple into a normal operating state, starting testing temperature and acquiring data, and displaying and storing the data on the computer; and (2) starting a linear stepped motor, regulating the front and rear positions of the temperature measurement probe, and measuring the temperatures of other positions in the boundary layer temperature field. The method has the advantage that temperature distribution in boundary layers of a vertical plane, a horizontal plane and the surface of rotating cylinder equipment can be directly measured.
Description
Technical field
The present invention relates to the temperature measurement technology field, relate in particular to a kind of boundary layer temperature measuring method.
Background technology
The boundary layer temperature measurement is the problem that often runs in the thermal conduction study research.Because the boundary layer size is generally all smaller, directly measure the restriction that receives multiple factor, difficulty is bigger, so mostly measurement means commonly used is contactless indirect method, measuring error is bigger, directly has influence on experimental result.Therefore, find a kind of direct measuring method little to boundary layer perturbation, that measuring accuracy is higher just to seem particularly urgent and necessary.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of can be accurately and record a kind of boundary layer temperature measuring method of boundary layer temperature field distribution fast.
A kind of boundary layer temperature measuring method of the present invention, it may further comprise the steps:
(1) places the boundary layer temperature field to need the position of test temperature probe, thermopair is linked to each other with computer with data collecting instrument successively, and debug normal operating conditions, begin the probe temperature line data collection of going forward side by side, show on computers then and store;
(2) open linear stepping motor, the front and back position of adjustment temperature probe, the temperature of other position in the Measured Boundary layer temperature field.
Advantage of the present invention:, can accomplish the direct measurement of Temperature Distribution in perpendicular, horizontal surface and the rotor equipment surface boundary layer through the method that the present invention proposes.
Description of drawings
A kind of boundary layer temperature measuring method measuring principle synoptic diagram that accompanying drawing proposes for the present invention.
Embodiment
Describe the present invention below in conjunction with accompanying drawing and instantiation.
Like a kind of boundary layer temperature measuring method of the present invention shown in the drawings; It may further comprise the steps: (1) places the boundary layer temperature field to need the position of test temperature probe 1; Thermopair is linked to each other with computer with data collecting instrument successively; And debug normal operating conditions, the line data collection of going forward side by side of beginning probe temperature shows on computers then and stores; (2) open linear stepping motor 3, the front and back position of adjustment temperature probe 1, the temperature of other position in the Measured Boundary layer temperature field.Preferably thermopair is fixed into
shape on probe bracket; So just guaranteed that one section thermocouple wire is parallel with wall; Be in boundary layer isothermal region to be measured, thereby improved measuring accuracy.
(1) thermopair is fixed into
shape and processes temperature probe on probe bracket; Place the boundary layer temperature field to need the position of test temperature probe 1; Thermopair is linked to each other with computer with data collecting instrument successively; And debug normal operating conditions; The line data collection of going forward side by side of beginning probe temperature shows on computers then and stores; (2) open linear stepping motor 3, the front and back position of adjustment temperature probe 1, the temperature of other position in the Measured Boundary layer temperature field.
Through testing:, when environment temperature is 15 ℃, be 68.95 ℃ from temperature for the 1.6mm place from span when wall surface temperature is 80 ℃; Is 36.45 ℃ from span from the temperature for the 3.2mm place; When the temperature that leaves for the 4.8mm place from span is 27.35 ℃.Method is simple.
Claims (2)
