Numerical calculations of the Moby Dick experiment by means of unsteady relaxation model

Mariusz Banaszkiewicz, Dariusz Kardaś
The paper presents numerical calculations of the Moby Dick experiment by means of the nonequilibrium relaxation model. Calculations are made using a computer code for solving non-steady flow problems. An interesting problem discussed in the paper is an appropriate choice of correlations for the relaxation time as well as a suitable value of the friction factor which have an effect on the process of vapour production in the model. The obtained numerical results appear to be in a reasonable agreement with the experimental data. This agreement speaks in favour of the homogeneous relaxation model as a useful tool for describing critical flows of water and vapour.
