General User Input Values Physics Used Displays

General

Component 76 is a component with external calculation. This means that the calculation is not done by EBSILON^®Professional, but else by an external program (Dll), which the customer must provide.

Without this program, it is not possible to include this component to your cycle.

Component 76 was developed together with ABB (later Alstom) to integrate Alstom reheat gas turbines in EBSILON^®Professional.
EBSILON^®Professional provides the framework for the calculation while the calculation itself is done by an internal Alstom program.

The parameters marked in blue are reference quantities for the off-design mode. The actual off-design values refer to these quantities in the equations used.

Generally, all inputs that are visible are required. But, often default values are provided.
