Abstract Lean Blow-Off (LBO) is of great significance for propulsion systems, and developing
an efficient LBO prediction method can technically support combustor design. In this paper …

The prediction of lean blowout (LBO) limits is very important in the combustion design
process. Several LBO semi-empirical correlations are proposed to estimate the LBO …

The lean blowout (LBO) limit is a crucial performance for aircraft engine combustors. It is
essential to obtain the LBO limit during the design stage of the aircraft engine combustors …

A method named characteristic curve of flame volume is achieved for lean blowout
predictions on the basis of the improved Lefebvre's model and simulated reacting flows …

The lean extinction limit is one measure of the stability of combustion systems. Over the past
60 years there have been many papers on the extinction of bluff body flame holders. Early in …

Bluff body stabilization of flames is a commonly employed technique for combustion
applications, such as thrust augmentors. These combustors are usually required to operate …

This study systematically investigated the Lean Blowoff (LBO) limits of Two-Dimensional
(2D) bluff-body stabilized premixed flames by varying the air mass flow rate, inflow …
