Combustion noise of stationary gas turbines or aero engines is associated with unsteady heat release that creates temperature fluctuations or so-called entropy waves (hot-spots). When accelerated in the turbine located downstream of the combustor, th

When modeling gas turbine sound emissions an important boundary condition is the acoustic reflection coefficient at the engine exhaust. Here, the flow discharges into atmosphere at elevated temperature and high flow velocity. The exit reflection coef

Combustors of modern gas turbines for power generation and mechanical drive are predominantly operated in premixed mode, which is sensitive to coupling between flame dynamics and combustor acoustics. In practice, combustor flames tend to drive instab

Solar photovoltaic panels (PV) provide great potential to reduce greenhouse gas emissions as a renewable energy technology. The number of solar PV has increased significantly in recent years and is expected to increase even further. Therefore, accura

The thermoacoustic stability of gas turbines depends on a balance of acoustic energy inside the engine. While the flames produce acoustic energy, other areas like the impingement cooling system contribute to damping. In this paper, we investigate the
