Online Seminar on Integrating a Hydrogen-Air Rotating detonation combustor into a gas turbine power plant by Prof. Guillermo Paniagua
Abstract
In this presentation, we will review recent progress to develop a compact combustor-turbine strategy to transition the high-speed, unsteady flow from rotating detonation combustors to industrial turbines.
First, we will discuss the evaluation of losses in a rotating detonation combustor based on measurements and CFD. The structure of the detonation waves is characterized using Chemiluminiscense and OH Pll F. The end wall pressure is monitored using pressure sensors and heat flux gauges. The exhaust conditions are evaluated using Pitot probes, FLASH, and CARS.
Second, we will discuss optimizing the transition from the combustor to the turbine. The turbine has been optimized using a multi-objective strategy leading to a new type of turbine configuration with significant diffusion near the end walls. The optimal design will be first tested at warm conditions and then finally at hot conditions coupled with the detonation combustor.
Finally, to predict the performance of the future power plant, we use an engine model based on the NASA T-MATS software. We will review our progress in the modeling of the combustor alone, using the method of characteristics.
This research is funded by the US Department of Energy and capitalizes on the following:
- Experimental facilities for testing detonation combustors at high pressure.
- A tri-sonic turbine facility.
- A new engine test facility donated by Rolls-Royce Liberty Works.
- Advanced high-speed laser diagnostics, surface sensors, and aerodynamic probes.
- High-fidelity computational fluid dynamics.
