Large eddy simulations (LES) of combustion instabilities are often performed with simplified
thermal wall boundary conditions, typically adiabatic walls. However, wall temperatures …

The occurrence of combustion instabilities in high-performance engines such as gas
turbines is often affected by the thermal state of the engine. For example, strong bursts of …

The flame in a gas turbine model combustor close to blow-off is studied using large eddy
simulation with the objective of investigating the sensitivity of including different heat loss …

Abstract We investigate the Flame Transfer Function (FTF) of a lean-premixed, laminar slit
flame numerically. Based on the reference case at atmospheric pressure, we investigate four …

Abstract Physics-Informed Neural Networks (PINNs) have emerged as a promising tool to
model flow fields by embedding physical laws into neural networks and thereby reducing the …

Combustion instabilities in gas turbines are associated with increased pollutant emissions,
inconsistent power or thrust output, and premature wear and failure of components …

The present study investigates the thermoacoustic instability for triangular bluff-body stabi-
lized flames using high fidelity Large Eddy Simulations with finite-rate chemistry. The study …

Typical gas turbine combustor (GTC) and high-pressure turbine stage generally employs
10,000 to 100,000 small passages of cooling holes. Such an arrangement protects the solid …

In modern day gas turbine hot sections, active cooling of liner walls is critical due to
extremely high temperatures and long continuous operation. Reduced thermal stress …

The inclusion of conjugate heat transfer (CHT) in simulations of flame dynamics and
thermoacoustic stability is a recent development promising higher accuracy than established …
