Integration Between a Secondary Air System Network and A Thermal Whole Engine Model for Gas Turbine Design, Using Simcenter 3D 

Secondary Air Systems (SAS) are crucial in gas turbine engines, ensuring the reliable performance of both the individual components and the entire engine system. The primary functions of SAS are to deliver cooling airflow to engine components, seal bearing chambers, and regulate bearing axial loads. Accurately modeling these flows and their thermal interactions with metal components is essential for enhancing the performance and reliability of a gas turbine engine.

This paper presents an integration between Flow Simulator and Simcenter 3D by Siemens that pushes the Secondary Air System design to the next level. The integration was designed by Baker Hughes and developed by Maya HTT.

The paper will show how it is possible to:

- Import flow network geometry from Flow Simulator to Simcenter 3D on top of the 2D or 3D turbomachinery model.

- Automatically mesh the flow geometry in Simcenter 3D.

- Import flow network results from Flow Simulator and apply them as boundary conditions, such as temperature, pressure, mass flows, and swirl, in the Simcenter model.

- Handle flow cavity by applying the appropriate pumping and windage heat boundary conditions.

- Apply heat transfer coefficient using specific thermal correlation.

- Solve the model in Simcenter 3D and retrieve key results on the metal side as well as on the secondary flow duct side.

- Use custom tools to post-process results that matter for turbomachinery designers and analysts, at the chamber, element, and cavity levels.

A seamless integration between secondary flow design and thermal simulation analysis can accelerate the design time by as much as three times and reduce the number of iterations. By allowing automation and integration to take care of the tedious tasks typically involved in turbomachinery design, designers and analysts can focus on more creative activities.
