Modelling thermohydrodynamic processes in steam-generating channel

The problem of modelling nonstationary coolant flow as a part of the channel reactor full-scale model is discussed. The liquid model of coolant one-dimensional flow with empirical corrections for nonequilibrium drop and steam slip is considered. The possibility of flow reverse both at separate sections and in the whole circuit is taken into account when formulating the problem. An implicit space-symmetrical difference scheme is composed on the base of the conservation equations. The results of the program verification using the standard tests are given. 4 figs
