Numerical calculations of pressure oscillations in a side-dump ramjet engine [PDF]

, 1984
Pressure oscillations in a side-dump ramjet engine have been studied, using a one-dimensional numerical analysis. The engine is treated in two parts; the inlet section, including a region of two-phase flow downstream of fuel injection, and a dump ...

A deep learning-based approach for flow field prediction in a dual-mode combustor

Propulsion and Power Research
Accurate acquisition of the distribution of flow parameters inside the supersonic combustor is of great significance for hypersonic flight control. It is an interesting attempt to introduce a data-driven model to a supersonic combustor for flow field ...

Prediction of the flow inside a micro gas turbine combustor [PDF]

, 2008
The main purpose of this study is to predict the flow dynamics inside a micro gas turbine combustor model. The flow field inside the combustor is controlled by the liner shape and size, wall side holes shape, size and arrangement (primary, secondary and

Investigations of Combustion Performance in LPP Combustor

Journal of Applied Fluid Mechanics, 2017
A Lean Premixed Prevaporized (LPP) low-emission combustor which is applied with the combustion technology of staged lean fuel is developed. To study the cold flow dynamics and the combustion performance of the LPP combustor, both experimental tests using
