Dynamic Modeling and Simulation of Gaseous Systems

A computer-based model for analyzing air/gas system dynamics has been developed. A set of generic elements are interconnected by generalized junction structures to represent a variety of system configurations. The response of pressure, flow, temperature and heat transfer rate at any point or station in a system is then determined due to a wide range of fluid, thermal and mechanical disturbances. The model has been used to analyze furnace implosions in fossil fuel power plants. A coal-fired plant model has been constructed and simulated. The model simulations of the furnace pressure excursions are in close agreement with the data from the field tests.
