Baumann Centenary Wet Steam Conference 10-11 September 2012

Studying at Cambridge

Welcome to the Baumann Conference Website

One Hundred Years of Wet Steam Research ...

In 1912 K. Baumann published his celebrated ‘one percent for one percent rule’ concerning the decrease in efficiency of steam turbines operating in the wet region (K. Baumann, 1912, Recent Developments in Steam Turbine Practice, J. Instn. Elec. Engnrs, 48: 768-842). On page 830 he wrote:

Tests have shown that when the steam is wet the efficiency is reduced. Assuming that the efficiency follows a continuous curve for superheated and wet steam when plotted with entropy as a basis, the efficiency will change by 1 per cent. for each 1 per cent. variation in wetness.

Because of the undoubted influence of the Baumann Rule on wet steam turbine design, we have decided to mark the centenary of this publication with a conference on the latest developments in wet steam theory, experimentation and practice. The conference will take place in Cambridge UK on Monday and Tuesday, 10-11 September 2012.
