Abstract

In this paper the development of a dynamic systems CFD simulation code for the modeling of HTGR power plants will be discussed. The basic methodology of the numerical method with is known as an implicit pressure correction method (IPCM) will be presented. The method is capable of solving the pressure distribution, mass flow rate and temperature through an arbitrarily structured, physically realistic thermal-fluid system. The different component models used in the modeling of a typical HTGR power plant will also be presented. A loss of load incident for a three shaft recuperative Brayton Cycle will be modeled and the results obtained from the simulation will be discussed to demonstrate the utility of the code. The simulation will be used to show both the steady-state and dynamic ability of the method.
