Abstract

This paper deals with computerized supporting techniques of a numerical simulation of complex and large-scaled engineering systems like nuclear power plants. As an example of the intelligent support systems of dynamic simulation, a proto-type expert system is developed on an expert system development tool to support the selection of mathematical model which is a first step of numerical simulation and is required both wide expert knowledge and high-level decision making. The expert system supports the selection of liquid-vapor two phase flow models (fluid model and constitutive equations) consistent with simulation purpose and condition in the case of thermal-hydraulic simulation of nuclear power plants. The possibility of the expert system is examined for various selection support cases by both investigation of the appropriateness of the selection support logic and comparison between support results and decision results of several experts.
