Difference method for calculation of the dynamics of a steam-generating channel with compressible two-phase coolant

For the calculation of dynamics of a steam-generating channel with compressible two-phase coolant a partially implicit hemegeneous difference method realized by scalar run is suggested. The difference method is meant for the calculation of subsonic fluid flows. The use of the elements of implicit methods permits to envisage a greater pitch of integrating by time than the one determined by the Kurant condition by coolant. As for the machine time per one pitch of integrating the numerical method is comparable with solution on the basis of integral model of momentum conservation. Operation ability of the algorithm suggested is tested taking two standard problems as examples. 8 refs.; 5 figs
