Computational Studies of the Recondensation Process in a Tank with a Cryogenic Filling

Abstract

In nowadays the best way to carry an operating body such hydrogen or nitrogen for example it’s to carry it in liquid state and low temperature which is cryogenic state. In this work it will be shown a computational studies of the recondensation process in a tank with a cryogenic filling, and also a promising technologies in the cryogenic filling tank that have been realized at the laboratory of Samara University. The computational studies carried out allow us to draw the following conclusion that during regasification of a cryoproduct in the cryogenic filling tank, recondensation of a part of the gasified product occurs due to the temperature difference between the wall of the thermos and the inner wall of the cryogenic filling tank. This process is observed at the beginning of regasification (in the first 3-5 minutes), and the intensity of this process is low and amounts to about 2-8%.
