Optimizing Centrifugal Compressors for a Wide Operating Range
October 19th, 2017 | Start Time 10:00 – 11:00 AM EDT
Centrifugal compressors are highly engineered products. The reach of these machines spans many different applications including aerospace engines, automobile turbochargers, chemical processes, air conditioning, supercritical CO2, micro gas turbines, military equipment cooling, blowers, vacuum cleaners, and many others. Typically, a compressor is created for one operating or design point. However, operation of these machines is not limited to only this regime. In fact, some machines rarely operate at this point, making off-design performance more important in these cases. This raises the question of what factors must be taken into account when optimizing a centrifugal compressor for wider range?
SoftInWay supports a number of clients on centrifugal compressor projects and trainings as well as provides them with the tools needed to achieve their project goals. Through the use of AxSTREAM® for centrifugal compressor design, users can complete a number of tasks including quick generation of preliminary geometries, blade profiling, load analysis, off-design performance calculations utilizing streamline analysis, 3D CFD analysis and more.
This one-hour webinar will begin with a brief introduction to various applications of centrifugal compressors and will rapidly advance to the design and optimization of these machines with an emphasis on flow range. Off-design performance and key factors which affect this performance will be considered. The webinar will conclude with a software presentation walking attendees through the main design steps utilizing AxSTREAM® for an integrated approach.
The webinar session will include:
- An overview of centrifugal compressors and their application
- A theoretical background and terminology overview (stall margin, surge margin, flow coefficient, corrected parameters, etc.)
- The effects of different design parameters on flow range
- Mechanisms of stall, surge, and choke
- Various studies in AxSTREAM® including:
- Design for wide range application
- Ported shroud (bleed slot) modeling
- Use of vaneless diffusers versus vaned diffusers
- Variable speeds and IGVs to improve range
Who should attend:
- Aerospace, mechanical, and development engineers working on the design, modification, or upgrade of centrifugal compressors
- Engineers, scientists, and managers starting or advancing in centrifugal compressor design and analysis
- Program managers who want to bring new design capabilities in-house
- Engineering students looking to expand their knowledge and/or work on centrifugal compressors
