- Reducing the loss in a steam turbine exhaust hood results in a lower static pressure at the exit from the turbine and hence increased power output. The results from calculations carried out using established advanced numerical methods to couple the flow through the turbine blades with the exhaust hood flow are compared with our new approach. Our novel approach demonstrates the potential for improving the accuracy of predictions at design and off-design conditions from adopting these techniques. The work is of interest to large steam turbine OEMs globally and to other academic researchers in the field.
