| Summary: | To conduct experimental investigations of the drying process of a closed container, taking into account
the opening of a leak channel in a weld, an experimental research stand, an experimental container
and experimental samples with model leaks of different sizes are designed and manufactured. The
scientific problem of experimental research has been formulated, a program and methods for conducting
experiments have been developed. Requirements for metrological equipment have been formed
and the measurement error of temperature, humidity and pressure has been determined. Preliminary
experiments are carried out on wetting the experimental container and experimental samples with a
model liquid and clogging the leak channels, as well as on drying the inner surface of the experimental
container wall with a convective gas flow and conductive heating of the wall until the leak channels
clogged with liquid are opened. The dependences of the change in temperature of the liquid, air, wall
of the experimental container, experimental samples and pressure in the experimental container are
obtained over the time of the experiment during wetting and drying of the experimental container and
experimental samples. The parameters of thermal exposure at which the leak channels is opened within
a specified time are determined. |
