Introduction

Radial compressors

This short course is the regular course on radial compressors thought at VKI to the turbomachinery students specializing in compressors in the context of the “Research Master in Fluid Dynamics”. It provides an overview of the present knowledge and flow models and intends to provide a good background for the people interested in the aerodynamic design of radial compressors.

This 5 day course is now made available to a limited number of people from outside VKI. Lectures and exercises are given by Prof. R.A. Van den Braembussche and Prof. T. Verstraete.

Courses start everyday at 8h45 and finish at 17h00 (at 15h on Friday).

Programme

  • Applications and achievable efficiency
  • Transformation of energy in radial impellers and performance maps
  • Three dimensional flow in impellers
    • Blade loading
    • Two zone modeling
    • Slip factor
    • Disk friction
    • Secondary flows (mechanisms and control)
  • Vaneless and vaned diffusers
  • Inlet geometries and Inlet Guide Vanes
  • Stability and range:
  • Rotating stall (types and control)
  • Surge (physics and control)
  • Flow and loss mechanisms in volutes
  • Return channel flow
  • Impeller response to circumferential distortion (radial forces and pressure fluctuations)
  • Real flow effects:
    • Reynolds number
    • different gasses, scaling
  • Design of radial impellers (inverse design and optimization, optimum velocity distribution)
  • Design exercise using VKI software

Fee & Registration

Register here

Considering the limited number of participants it is highly recommended that the registration form is sent at the latest 15 days before the beginning of the course. A letter of acceptance and additional information will be sent on receipt of the application form.

Courses start everyday at 8h45 and finish at 17h00 (at 15h on Friday).

Lecture Series Fees

Type 1: Permanent residents of NATO countries funding VKI: Belgium, Bulgaria, Croatia, Czech Republic, France, Germany, Greece, Hungary, Iceland, Italy, Luxemburg, Norway, Portugal, Romania and Turkey
Type 2: Permanent residents of NATO countries not funding VKI or NATO partner countries
Type 3: Permanent residents of non -NATO countries

For PhD candidates and undergraduate students: The request to be considered for a discount must accompany the application to attend the Lecture Series, and the applicant must provide a recommendation letter from his or her professor; if not, the request will not be taken into consideration. All possible alternative sources of funding should be investigated before aid is requested under this scheme, so that those most in need will benefit.

REDUCTION

-50% for the 3rd & 4th participant from the same company.
