Abstract
At present the description of a heat and mass exchange under conditions of the frost formation at the level of cryogenic temperatures is urgent and still littlestudied. The most important for engineering practice in this case is the analysis of the thickness increase of the frost layer. Based on the experiments carried out the authors describe the main features of the frost formation on the wall at cryogenic impact linked with high temperature gradients and air moisture content both in the volume and near the frost surface. The dependences describing the dynamics of growth of the frost layer thickness are offered; they are compared with reliable experimental data. A satisfactory accuracy of dependences to conduct engineering calculations when designing the cryogenic equipment was shown. Based on the analysis of the dynamics of the frost layer growth the authors suggest a particular scheme of grouping panels of atmospheric gasifiers of cryoproducts that allows suppressing the increase of cryosediment on the working surfaces.
