ABSTRACT

The numerical three-dimensional model of heavy gas dispersion is considered. The conservative (upon mass) splitting method was used, solving pressure equation instead of the equation for temperature. The results of simulations compared with the laboratory experiments data. The comparison of the results against of calculations by the non-conservative splitting method is presented.
