がある。Thus, in elucidating the boiling mechanism of the liquid, (1) the micro-layer of the bubble when the boiling bubble is generated, (2) the observation of the boiling state of the liquid in the chamber, and (3) the inside of the chamber It is necessary to obtain the data on the heat convection and the temperature distribution such as the temperature gradient. However, in the conventional boiling observation apparatus, since the temperature distribution in the liquid was measured by the three resistance temperature detectors installed in the chamber as described above, three resistance temperature detectors were installed. Temperature can be measured, but the temperature distribution such as heat convection and temperature gradient during that time can be estimated from the measured temperature at three points, but for the part that is out of the position where the resistance temperature detector is installed. It is difficult to estimate the three-dimensional temperature distribution in the entire chamber. In order to solve these problems, it is possible to arrange the RTD in the entire chamber for measurement, but in that case, the existence of the RTD disturbs the boiling state of the whole liquid, and so on. There are problems that arise.

設けられた観測光路を透過する。In the boiling observation device 19 using the Schlieren optical system, the temperature distribution in the chamber 12 is three-dimensionally measured as described above. As shown in the figure, after the laser light output from the He—Ne laser oscillator tube 01 is expanded by the spatial filter 02, a part of the light direction is bent by the beam splitter 04. Using the bent light, the next beam splitter 05 separates the observation light 1 passing through the observation light path passing through the chamber 12 and the reference light. The reference light is further split into two reference lights by the beam splitter 07. Here, the reference light that is bent at a right angle by the beam splitter 07 is referred to as reference light 1, and the reference light that travels straight through the beam splitter 07 is referred to as reference light 2. The observation light 1 that has passed through the chamber 12 intersects again with the reference light 1 at the beam splitter 14, where a phase difference occurs,
By observing the interference state of light due to the phase difference with a CCD camera, the temperature distribution of the cross section of the observation optical path of the chamber 12 can be measured. Further, the observation light 2 traveling straight through the beam splitter 04 bends the direction of the light by the mirror 11 and passes through the observation light path provided in the lateral direction of the chamber 12 orthogonal to the observation light path through which the observation light 1 passes.

CCD camera 24
By observing at, the temperature distribution in the cross section orthogonal to the cross section in which the temperature distribution can be measured by the observation light 1 can be measured. As described above, according to the present embodiment, the temperature distributions of the two cross sections of the chamber 12 which are orthogonal to each other can be measured, and thus the three-dimensional temperature distribution in the chamber 12 can be observed by synthesizing and observing the temperature distributions.

When the thickness d of the observation fluid portion inside is set to about 10 cm and a Ne-Ne laser having a wavelength λ of 632.8 mm is used as a light source, in order to observe one or more interference fringes, Δn = λ · N / d = 632.8 x 10 -9 / 1/10 x 10 -2 = 6.3
When 28 × 10 −6 boiling liquid is water, the change in refractive index per 1 ° C. is about 1 × 10 −4 / ° C. (at 20 to 30 ° C.), so the measurement accuracy δ is δ = 6.328 × 10 -6 / 1 × 10 -14 = 0.063 ° C <0.1 ° C, which is the measurement accuracy of the conventional resistance temperature detector ± 0.5.
It can be observed with an accuracy of more than 5 times the temperature.

The light that does not reflect at the bottom of the glass plate heater 09 and further does not reflect even boiling bubbles and that passes through the chamber 12 is used as the observation light 2 in the boiling observation device 19. The two reflected lights are bent by the beam splitter 10 toward the CCD camera 18. CC

This light source is an illumination 28 installed in the lower part of the chamber 12, and this illumination illuminates the bubbles inside the chamber 12. In FIG. 3 showing a conventional example, the device for observing the boiling state of the whole liquid is designed to observe the same plane as the optical system of the Fizeau interferometer device, but the boiling observation device is installed. Therefore, the planes perpendicular to these planes are observed. However, the purpose is to observe the state of fluid boiling under microgravity, where the influence of gravity is small, and this difference has no problem.
