The use of gas-dynamic flame stabilization in afterburner combustion chambers of aircraft gas turbine engines

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2017
It is impossible to abandon the use of the afterburner combustion chamber in designing advanced gas turbine engines. Well-known and well-established structural designs of afterburners were developed several decades ago and do not meet the requirements ...

Liquid ammonia spray combustion in two-stage micro gas turbine combustors at 0.25 MPa; Relevance of combustion enhancement to flame stability and NOx control

Applications in Energy and Combustion Science, 2021
The development of liquid ammonia spray combustion technology is expected to reduce the cost and size of gas turbines otherwise fueled with gaseous ammonia. However, successful studies on this topic are scarce due to the difficulty in flame stabilization.

Analysis of flame stabilization limit in a cylindrical of step micro-combustor with different material through the numerical simulation

MATEC Web of Conferences, 2018
The flame stabilization limit on micro-combustor had studied to support the micro power generator system. Micro-combustion became the crucial components in a micro power generation system as heat resource that will be converted into electricity. However,
