The speed of the experimental technique (10 MS/s) and small dimensions of the measurement area (9 μm) have opened new possibilities for monitoring the initial stage of boiling-up. When using a double-probe scheme, the fact of measuring the prognostic signal at different times by two sensitive elements of the optical probes was discovered. Based on the experimental results, a hypothesis was formulated regarding the local character of the appearance of the perturbation source generating the observed signal in a superheated liquid. An estimate was obtained for the rate of perturbation propagation in a wide variation range of the degree of liquid superheating \\\\expert2\\NBO\\Technical Physics Letters (Письма в ЖТФ)\\2013, v. 39, N. 8, p.751.pdf |
