Validation of a non-contact technique for torque measurements in wind turbines using an enhanced transient FSV approach (2019)
Journal Article

In-service turbine monitoring is essential for maximizing the wind energy contribution to the global energy budget. Measurement of turbine shaft torque under transient wind conditions is fundamental to develop reliable condition monitoring techniques...

Efficient Methods for Predicting Low Pressure Steam Turbine Exhaust Hood and Diffuser Flows at Design and Off-Design Conditions (2015)
Journal Article

The exhaust hood of a steam turbine is an important area of turbomachinery research as its performance strongly influences the power output of the last stage blades (LSB). This paper compares results from 3D simulations using a novel application of t...

The influence of condenser pressure variation and tip leakage on low pressure steam turbine exhaust hood flows (2014)
Journal Article

This paper aims to highlight the importance of the accurate computational modelling of both the inlet and outlet exhaust hood boundary conditions. The computations presented are calculated using the public domain low pressure exhaust diffuser test ca...

A Novel Method of Coupling the Steam Turbine Exhaust Hood and the Last Stage Blades Using the Non-Linear Harmonic Method (2013)
Presentation / Conference Contribution

The exhaust hood of a steam turbine is a vital area of turbomachinery research its performance strongly influences the power output of the last stage blades. It is well known that accurate CFD simulations are only achieved when the last stage blades...

A Seal Assembly (2013)
Patent

The present invention relates to a seal assembly for use in between two components between which there is relative rotational movement, particularly but not exclusively, a shrouded axial flow turbine rotatably mounted within a turbine housing in a tu... Read More about A Seal Assembly.

A Generic Steam Turbine Exhaust Diffuser with Tip Leakage Modelling and Non-Uniform Hood Outlet (2013)
Presentation / Conference Contribution

This paper advances the work of Burton et al. (2012) to highlight the significance of the last stage blade tip leakage jet on the flow structure in the low pressure (LP) steam turbine exhaust hood, widely regarded as being significant in other publis...

Measurement and Computation of Energy Separation in the Vortical Wake Flow of a Turbine Nozzle Cascade (1999)
Journal Article

This paper describes the observation, measurement, and computation of vortex shedding behind a cascade of turbine nozzle guide vanes that have a blunt trailing edge. At subsonic discharge speeds, periodic wake vortex shedding was observed at all time...
