Short Abstract: This one hour demonstration webinar will demonstrate application of 3D inverse design code TURBOdesign1 coupled with automatic optimization code TURBOdesign Optima to multi-point, multi-objective and multi-disciplinary design of axial and centrifugal compressors.

The demonstration will cover three practical examples:

  • Multi-disciplinary design optimization of a centrifugal compressor impeller for high efficiency and low mechanical stress by using Multi-objective Genetic Algorithm (MOGA)
  • Multi-point, multi-disciplinary design optimization of an industrial centrifugal compressor impeller for high efficiency at multiple operating points subject to maximum allowable stresses constraints by using Design of Experiments (DoE), Response Surface modelling (RSM) and then running MOGA on the response surface
  • Multi-point design optimization of an axial compressor rotor and stator stage for high efficiency at multiple operating points via DoE + RSM and MOGA

The webinar will show how the inverse design method can be used to easily parametrize the blade with few design parameters but covering a large part of the design space. Also it will be shown how the range of the design parameters can be set within a feasible range and how inverse design optimization automatically satisfies the required specific work for each design, hence resulting in substantial saving in computational time. Furthermore, the importance of accuracy of the response surface will be discussed by using detailed error analysis.

A 15min Q&A Session will be held at the end of the Webinar to answer participants’ questions.

Who should attend: All engineers involved with the design and analysis of axial, mixed-flow and centrifugal compressors are encouraged to attend this demonstration session.
