Thermodynamics Approach to Determine a Gas Turbine Components Design Data and Scaling Method for Performance Map Generation

A major impediment to the development of
component–based engine models is the lack of available
component data. These data are usually proprietary of the
engine manufacturers and the normally available
information is scanty. The estimation suitable component
performance map remains, at best, a difficult task. When
component performance is not available the nearest method,
of estimating compressor performance such as the scaling
technique have been used successfully to model the turbine
and compressor. In using scaling technique, the difficulty of simulating existing gas turbine is lack of design data
available to the researcher, as the manufacturer gives only
the bare minimum data required for safe operation of the
plant. Without design data it is very difficult to
mathematically model the plant. Therefore; this study
illustrate how to find the design data with the minimum
available information using the basic thermodynamic laws
and use of scaling method to produce a new detailed
performance map from a known map with their design data.
