Combustion instabilities: basic concepts / Ben T. Zinn and Timothy C. Lieuwen -- Combustion instabilities in industrial gas turbines : Solar Turbine's experience / Kenneth O. Smith and James Blust -- ...

Engineers have long battled a problem that can cause loud, damaging oscillations inside gas turbines and aircraft engines: combustion instability. These unwanted pressure fluctuations create ...

Combustion dynamics investigates the coupling between unsteady heat release and pressure waves in reactive systems, encompassing gas turbines, industrial burners and propulsion devices. When ...

As US utility companies replace coal-fired power plants with natural gas, a collaboration between two parties is contributing to efficiency gains in GE's H-class gas turbines. GE researchers produced ...

Air and fuel mix violently during turbulent combustion. The ferocious mixing needed to ignite fuel and sustain its burning is governed by the same fluid dynamics equations that depict smoke swirling ...

Hydrogen is a key carbon-free energy carrier for a sustainable future, but its lean combustion often suffers from thermodiffusive instabilities that ...

The Combustion Dynamics group deals with combustion dynamics processes in rocket combustion chambers. This includes the experimental investigation of propellant injection into the combustion chamber, ...

Dr. Lee is an experimentalist interested in studying turbulent and spray combustion, including high-pressure diesel and gasoline spray and fundamental turbulent flames. Dr. Lee’s research interests ...

This combustion concept is characterised by the injection of air-fuel mixtures into the combustion chamber in the form of jets with high flow velocities. The arrangement of the jets results in a ...

This figure illustrates the "scale-free" nature of the turbulence network during spray combustion instability. (A) The spatial distribution of node strength reveals highly connected hubs (red regions) ...
