Experimental investigations of opening leaks in a welded seam of a closed container under thermal and acoustic influences

Abstract

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.
