Numerical modeling of a honeycomb head for a regenerator used in microcryogenic gas systems
We employed numerical analysis methods to assess time between failures for microcryogenic gas systems at the design stage, taking into account various factors, including structural parameters. We suggest using multi-factor heat, gas and fluid dynamics analysis, 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 numerically 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 dependences, which showed a high degree of convergence with Tanaka’s and Blase’s dependencies. This comparison forms the basis for using the model supplied in the mathematical model for further computations.
