Acceleration of combustion computation fluid dynamics simulations through machine learning
This work demonstrated the acceleration of combustion computational fluid dynamics simulations through Deep Operator Networks (DeepONets), achieving up to an 18 times speedup in the chemical source term evaluation. Another numerical experiment showed an overall reduction of approximately 30% in …

A method for the numerical analysis of combustion instabilities with an application to afterburner screech
… thermoacoustic oscillations in gas turbine combustion systems by computational means. A framework is laid out to predict numerically the frequency and stability of thermoacoustic oscillations, with focus on the high frequency screech instability of afterburners. A hybrid numerical method is …

Plasma Assisted Ignition in a Three-dimensional Scramjet Combustor with a Photon-preserving Radiation Model
… discharges (NRPD) can affect and improve the combustion characteristics in a high-speed fluid flow that simulates scramjet conditions. This is done by creating a computational code that incorporates the effects of plasmas, high-speed fluid dynamics, combustion chemistry, and photoionization. …
