SSD Seminar Series with Thomas Hösgen, M. Sc.

6. Dezember 2021 @ 16:00 - 17:00

Thomas Hösgen, M. Sc. – High-Performance Computing for the Optimization of Modern Gas Turbine Cooling Systems

Simulation Data Lab Fluids, RWTH Aachen University


Climate change and its resulting consequences put an ever-increasing demand for more energy efficient gas turbines on the manufacturers of flight- and stationary gas turbines. To further improve the thermal efficiency of the turbines, manufacturers aim to raise the turbine inlet temperatures by increasing the combustion temperatures. This, however, results in higher demands on the turbine cooling systems. To ensure the safety towards component failure during machine operation, the existing cooling mechanisms need to be improved. Due to the complexity of experimental test facilities, the design of optimized cooling systems is strongly based on numerical design tools such as computational fluid dynamics (CFD).

In this presentation the current state-of-the-art CFD tools and their limitations, as well as the possibilities of modern more sophisticated high fidelity CFD methods in combination with high-performance computing (HPC) will be illustrated, by investigating the cooling systems applied at the rotor-stator disk cavity in modern gas turbines.
