Cooled Turbines

 As a film cooled turbine designer, your pursuit of improved gas turbine performance and fuel efficiency has put you on a path to smaller engine designs capable of withstanding heavy loads and extreme operating temperatures. 

These design conditions pose a great challenge.  How will you design efficient cooling schemes to counteract extreme operating temperatures?  How will you account for the stronger blade row interaction effects inherent in smaller axial gap designs?  And how can these issues be tackled in a timeframe suitable for design? 

Here's how we can help:

Accurate surface temperature prediction for improved cooling scheme design

Leverage the new conjugate heat transfer capabilities in Code Leo to accurately predict metal temperature and improve cooling scheme design.  Developed under an SBIR Phase II award from the United States Air Force, our streamlined procedure allows you to analyze any material and design of your choosing using temperature dependent material properties and industry standard unstructured mesh input.  With ADS CFD, complex features such as shaped holes with compound angle, trailing edge slots, pedestal chambers and turbulators can be analyzed with ease and tuned for optimum impact.

Robust "4D" analysis for time resolved flow insight

Incorporate the fourth dimension—time—into CFD analysis to gain critical flow insights needed to advance turbine durability and performanceWorried about high cycle fatigue?  Study blade row interaction effects to counter adverse aerodynamic loading.  Looking to enhance efficiency and operating range?  Conduct 4D studies to characterize adverse endwall secondary flow effects.  Take advantage of the ADS Workbench to simplify case configuration,  and choose from sector, scaled sector or full wheel unsteady analysis options to achieve the proper balance of accuracy and turnaround time.  

Design time application

Count on ADS to turn around your aero analysis in timeframes suitable for design. Simulations that routinely take days to generate can be completed in hours, returning precious cycles back for design optimization or faster time to market. ADS also finally makes unsteady analysis practical, delivering order of magnitude speedups that allow you to address adverse time dependent flow phenomena within tight design windows.   

Easy integration

Integrate conjugate heat transfer and unsteady analysis capabilities easily into your design optimization workflow through the use of text-based setup files and command line executables.

Makes sense.  Now what?
