Sankey diagrams made with e!Sankey

Whether you are working in energy management, analyzing material streams in a production system, or your tasks revolve around supply chain, logistics and goods being shipped:

Sankey diagrams created with e!Sankey will really improve the way you are visualizing energy flows and mass flows.

We are providing below Sankey diagrams that we like and that are worth sharing. These files can be downloaded in the .sankey file format and opened in e!Sankey (version 4 or 5).

The original: energy efficiency of a steam engine

The first illustration of energy flows using arrows proportional to the quantity was created by the Irish engineer Captain Matthew Henry Phineas Riall Sankey. Even back then it included many elements making Sankey diagrams so popular today. We have recreated this diagram using our software e!Sankey.

By the way, here is a little insight into the history of Sankey diagrams.

Another retro style diagram

Many generations of students and professionals have been using the 'Dubbel - Handbook of Mechanical Engineering'. It was first published back in 1914.

We have picked one classic black/white visualization of the "Heat Flow in a Boiler" from Dubbel's book and have recreated it in e!Sankey. It can be downloaded here.

The original retro look has been maintained with heat losses shown with a diagonal hatched pattern just in the original figure.

U.S. energy consumption per capita

This Sankey diagram shows energy use per capita in the United States for the year 2006. More recent data is available, but the general picture hasn't changed: Huge energy losses occur in electricity generation and combustion engines of motor vehicles.

The diagram has been created with e!Sankey 4 and is based on data by Lawrence Livermore National Laboratory (LLNL).

Material & process flow diagram

Using e!Sankey you can also show different flows within one diagram, e.g. materials and energy. This is very helpful, when you would like to view production processes holistically.

The following diagram shows, how such a production process can be illustrated.

The advantage of this illustration catches the eye immediately: losses and energy are displayed separately from the material flow from left to right.
