Rotating cavities
The components of modern industrial and aircraft gas turbines are subject to high thermal and mechanical stresses. The turbine inlet temperature has been constantly increased in recent years and is above the permissible material temperatures.
This has increased the power and efficiency of the machine, but has increased the demand for cooling air, which limits this increase. The optimum between high working temperatures and little cooling air is the goal of the design. Flow and heat transfer in rotating cavities and cooling technologies are the main subjects of current research.
Improving cooling technologies helps to increase efficiency and performance and reduces CO2 emissions from the machines.
