We employed numerical analysis methods to assess time between failures for microcryo-
genic gas systems at the design stage, taking into account various factors, including
structural parameters. We suggest using multi-factor heat, gas and fluid dynamics analy-
sis, based on integration of accumulated experience in experimental investigations and
numerical modelling. We provide an example of applying this multi-factor heat, gas and
heat dynamics analysis to analysing units of microcryogenic gas systems. We conducted
three-dimensional numerical modelling of structure and fluid dynamics in a honeycomb
regenerator as the primary risk-accumulating unit. We compared the results of numeri-
cally investigating the drag in the regenerator we modelled as a function of the Reynolds
number to the results of computations based on foreign researchers' correlation depend-
ences, which showed a high degree of convergence with Tanaka's and Blase's dependen-
cies. This comparison forms the basis for using the model supplied in the mathematical
model for further computations.
