Ellipse Law · Description

Ellipse Law: a easy tool to calculate pressures, mass flow and temperatures for off-design conditions in turbomachinery.

Ellipse Law calculates Stodola‘s Cone Law (also known as "The Law of the Ellipse") for turbomachinery.

At the beginning of the 20th century, Aurel Stodola (1859 – 1942) discovered the relationship between inlet pressure, outlet pressure and mass flow in steam turbines for various operating conditions.

Today, this law fundamental for calculation and control of turbines.

Programm features:

Define the boundary conditions for the design case of your turbine: mass flow, inlet and outlet pressure and - optionally - inlet temperature and calculate the data for each off-design load case:

inlet pressure by mass flow and outlet pressure
outlet pressure by inlet pressure and mass flow
mass flow by inlet pressure and outlet pressure

Each calculation can be done with or without temperature correction.
