Combustion and Flame. 223:295-306
Low-frequency combustion instabilities, and ultimately, engine-level dynamics in can-annular gas turbine combustion systems, are driven by acoustic interactions between adjacent combustors through an annular cross-talk section upstream of first stage

The prediction of self-excited combustion instabilities in a can-annular gas turbine combustion system is a significant challenge, mainly because the instabilities originate from the acoustic interactions between adjacent combustors via a cross-talk

In this study, an experimental facility with two combustion cans was built and successfully replicated the field boundary conditions for heavy duty gas turbine combustors. Each combustor consisted of multiple Dry Low NOx (DLN) fuel nozzles, represent

The identification of scattering matrix method is conducted using high fidelity Large Eddy Simulations. From a series of LES results, the scattering matrices of a plain orifice and a lean premixed nozzle are evaluated and compared with the correspond

A new model has been developed for describing the rheology of thixotropic fluids. The model accounts for hysteresis effects when the fluid goes through multiple shearing events. To demonstrate the model capability, a series of unsteady, three-dimensi

The cap shock pattern is observed in the plumes of over-expanded thrust optimized rocket nozzles at the low pressure ratios that occur during start-up and shut-down transients. These nozzles exhibit both free and restricted shock separation, and the
