Claim 5:
6. An experimental method of the narrow slit channel visualization experimental device under a six-degree-of-freedom motion condition according to claim 1, wherein water filling leakage detection and compression resistance experiments are carried out on the main circulation loop and the cooling water system before an experiment is started to ensure that the main circulation loop is leakage-free in a large-flow and high-pressure state;
before the experiment is started, the pressurizing circulating pump and the exhaust valve are started, gas in the main circulation loop is exhausted, all working media in the main circulating loop are kept to be single-phase water, and then tracer particles are injected; then, the exhaust valve is closed, and the voltage stabilizer is adjusted, so that the pressure of the main circulation loop is working condition pressure of an experimental target;
when the bubble monitoring system is started, the electric servo module is remotely controlled by the computer, and the two high-speed cameras and the particle image velocimetry measuring system are corrected according to set reference orientations;
when the cooling water system is started, valves of the indoor part and the outdoor part are kept in an open state, circulating pumps of the indoor part and the outdoor part are started respectively, and the cooling fan is started to accelerate cooling of a fluid in the cooling tower;
when the electric heating system is started, the heating power of the three-surface visualization experimental section and the S-shaped preheater is gradually and slowly increased, wherein a rise amplitude of the wall temperature of the three-surface visualization experimental section does not exceed 15 DEG C every time the heating power is increased, and after the wall temperature of the three-surface visualization experimental section and the flow of the main circulation loop are stable, next power rise operation is carried out until the inlet fluid temperature of the three-surface visualization experimental section reaches working condition temperature of the experimental target; and
when the six-degree-of-freedom motion simulation platform is started, the reference of each telescopic cylinder is corrected, a power supply of the driving system is started, the mechanical table body is raised to a certain height through the control system, enough space allowance is reserved for subsequent simulation of various motions, and a motion working condition of the experimental target is set for motion simulation.
