Simulation of partially premixed turbulent flames
, 2017 This work numerically investigates the turbulent partially premixed flames, which are ubiquitous in combustion powered devices. This combustion mode involves many physical complexities such as flame propagation in unevenly premixed mixture of fuel and oxidiser, turbulence/flame interaction in presence of mixture fraction gradients, triple flame ...

Large Eddy Simulation of a Swirl-Stabilized Pilot Combustor from Conventional to Flameless Mode
Journal of Combustion, 2016 This paper investigates flame and flow structure of a swirl-stabilized pilot combustor in conventional, high temperature, and flameless modes by means of a partially stirred reactor combustion model to provide a better insight into designing lean ...

Development of flamelet generated manifolds for partially-premixed flame simulations [PDF]
, 2011 Accuracy of simulations of combustion processes does not only depend on a meticulous description of the turbulent flow field, its accuracy and detail depends on the representation of combustion chemistry and its interaction with turbulence as well ...

Flame index measurements to assess partially-premixed flame models
, 2013 A method has been developed to measure flame index and was applied to a fuel-lean and a fuel-rich propane/acetone/air flame in a canonical, well-defined partially-premixed burner-the Gas Turbine Model Combustor (GTMC).

Numerical simulation of partially premixed combustion using a flame surface density approach [PDF]
, 2020 Partially premixed combustion is characterized by a variable equivalence ratio of the mixture in space and time, and where there are both lean and rich mixture zones.
