TURBOMACHINERY
Turbine Aerodynamics and Heat Transfer
Objectives
The laboratory deals with the design, testing and imporvement of axial turbines for aviation and power generation plants.
VKI investigates the aero-thermal performance of high-speed turbomachinery components found in gas turbine engines for aircraft propulsion. The research projects principally cover technologies for the high-pressure and low-pressure turbine modules. A large spectrum of aerothermal aspects of axial turbines is considered, ranging from fundamental studies on emerging technologies to the investigation of fully featured turbine hardware at TRL levels of 4-5.
A combination of computational and experimental methods to study the complex flow physics of axial turbines is used. The main strength is the experimental testing of turbine hardware with an extensive capability to take measurements on a wide variety of facilities for tests at low-speed and high-speed in cascade rigs as well as in a large-scale rotating machine.
