A numerical algorithm for calculating steady-state flow splits

It is generally necessary to initiate the mathematical simulation of a variation in the thermalhydraulic state of a nuclear reactor system over a period of time from an equilibrium or ''steady'' state characterized by a limited set of steady-state data estimates. Consequently, computer programs designed to simulate such nuclear reactor transients should include algorithmic logic to establish the steady state from a minimal and convenient set of the equilibrium data. Further, this steady-state initialization capacity should include the versatility of calculating the steady-state divisions of known single-channel fluid flows (rates) into separate channels or ''parallel flow paths'' on the basis of specified junction form loss coefficients and the other known equilibrium data. This paper is a presentation of an extension of a proven algorithm for determining the steady state when such flow splits are known a priori to the case in which corresponding junction form loss coefficients supplant knowledge of flow rate splits in the modeler's set of initially known steady-state data
