Combustor Liner

The liner cooling for GTX100’s annular combustor has been successfully tested. Because of high heat load at the flame attachment point, a good design is very important. The design presented here offers robustness and high performance, combined with no dilution. The cooling system is a turbulated convective design, which were experimentally investigated in a plastic (perspex) model of a full scale 60° sector of the combustor. The importance of a high performance liner cooling is obvious. This design generates low pressure drop, better combustion (circumferential even flow from the liner cooling) and it gives lower flame temperature (minimizes the emissions). The influence of disturbances on the cooling and burner performance is presented in this paper.

High Heat Load

A cooling entrance region for a modern annular combustor has been successfully tested. Because of high heat load at the entrance part of the liner, a good design is very important. The design presented here offers ultra-low dilution, robustness and high performance. The cooling system includes convective, film and impingement techniques, which were experimentally investigated in a plastic (perspex) model of a full scale 60° sector of a simplified combustor design. The importance of a high performance entrance is obvious. It generates low pressure drop, better combustion (circumferential even flow for the liner cooling) and it gives lower flame temperature (maximizes the air in the flame). Guidelines for the design of such an entrance are presented in this paper.

High Heat Load

Next-generation high-brilliance X-ray photon sources call for new X-ray optics. Here we demonstrate the possibility of using monolithic diamond channel-cut crystals as high-heat-load beam-multiplexing narrow-band mechanically stable X-ray monochromators with high-power X-ray beams at cutting-edge high-repetition-rate X-ray free-electron laser (XFEL) facilities. The diamond channel-cut crystals fabricated and characterized in these studies are designed as two-bounce Bragg reflection monochromators directing 14.4 or 12.4 keV X-rays within a 15 meV bandwidth to 57Fe or 45Sc nuclear resonant scattering experiments, respectively. The crystal design allows out-of-band X-rays transmitted with minimal losses to alternative simultaneous experiments. Only ≲2% of the incident ∼100 W X-ray beam is absorbed in the 50 µm-thick first diamond crystal reflector, ensuring that the monochromator crystal is highly stable. Other X-ray optics applications of diamond channel-cut crystals are anticipated.

High Heat Load

For shear driven mm-scale flows, the traditional boiler and condenser operations pose serious problems of degraded performance (low heat-flux values, high pressure drops, and device-and-system level instabilities). The innovative devices are introduced for functionality and high heat load capabilities needed for shear dominated electronic cooling situations that arise in milli-meter scale operations, certain gravity-insensitive avionics-cooling and zero-gravity applications.
