An Introduction to the Rank-n Nonlinear Harmonic Method

Announcements The flow field in turbomachinery is dominated by inherently unsteady flow features such as blade-row interactions, blade vibration, inlet distortions, or high thermal gradients. Perturbations due to propulsion-airframe integration, aircraft maneuvers, crosswind, and temperature non-uniformities coming from the outlet of combustors are just a few of the many sources that can undermine the performance, stability, and durability of gas turbine engines.

NUMECA's Nonlinear Harmonic method (NLH) enables a better understanding of the propagation of flow non-uniformities into turbomachinery components by accurately and efficiently modeling turbomachinery configurations that are subject to periodic variations.

This webinar will cover the latest development of the NLH method: the rank-n. This new feature unlocks the possibility of simulating unsteady phenomena across a theoretically limitless number of turbomachinery rows: turbomachinery engineers can now benefit from more realistic flow assessments, leading to more precise and reliable designs.

In this 40-minute webinar we will cover:

  • An introduction to the Nonlinear Harmonic Method.
  • What is the rank-n in the NLH method and
  • A case study of the propagation of hot streaks through several stages of an axial turbine.
  • What’s to come on NUMECA tools for turbomachinery simulations.
