Introduction

The simulation of the liquids and gases within a system is achieved by the use of complex mathematical models of each aspect of the commodity being considered. To ensure accurate realism the models deal with the behavior of the thermodynamics of the various liquids and gases within a system both when in equilibrium and non-equilibrium conditions, together with the fluid dynamics.

Outputs from the models are provided in the form of temperatures, pressures, rate of flow together with the status of valves and other equipment. When completed a typical model will encompass almost all aspects of a particular system required for its correct operation.

The other sections provide more detail in:

• The general structure of the models
• The areas of the chemistry and physics addressed within the models
• Specific modeling requirements resulting from the different systems within each model
• The malfunction capabilities provided
• The design process for the development of new models
