The research proposes an approximate analytical method for calculating the melting time
of a slush-like cryogenic product in a torus container when drain storing. We examine
the problem of finding the position of the interface between the pure liquid region and the
slush with an allowance for the heat flow from the walls and the area of pure liquid. We
accept the following parameters: the area of slush is isothermal and has a melting point
of the solid phase, the interface slush is pure liquid, a flat free surface of the liquid is sta-
tionary and has a saturation temperature at a given pressure. The temperature in the ar-
ea of pure liquid is linearly distributed. The approximate relations obtained allow us to
evaluate the melting time of a slush-like cryogenic product in the container without a de-
tailed calculation of the temperature fields in the pure liquid.
Keywords: cryogenic liquid, cryogenic product, drain storage, liquid, slush, melting,
container.
