Industrial Application in Turbomachinery, Automotive and General DesignTraining

Thursday training content

• Introduction to radial equilibrium in turbomachinery.
• How does radial equilibrium interact with the design conditions in the blade-to-blade plane
• Flow in turbomachinery cascades:
  • Introduction to incompressible irrotational flow. Relation between curvature and velocity gradient normal to streamlines.
  • Streamline curvature method: examples of use in e.g. u-bend, cascades.
  • Exact solution for basic potential flows, the concept of superposition.
  • Vortex panel methods for inviscid flow over airfoil.
  • Kutta condition, Kutta transformation.
  • Adapt the potential flow of airfoils to cascades with periodic boundary conditions.
  • Derivation of the relationship between blade loading and flow turning.
  • Use of potential flow to explain basic phenomena in cascades: optimal incidence, deviation, effect of solidity and blade thickness.
  • The use of inverse methods to adapt blade profiles to desired velocity profiles.
  • Design practices with respect to defining optimal velocity profiles. Controlled Diffusion Airfoils.
  • Mach number effects, introduction to unique incidence.
• Demo on the use of inverse methods on compressor and turbine blade.
