Theoretical analysis of superadiabatic combustion for non-stationary filtration combustion by excess enthalpy function [PDF]

Royal Society Open Science, 2020
The superadiabatic combustion for non-stationary filtration combustion is analytically studied. The non-dimensional excess enthalpy function (H) equation is theoretically derived based on a one-dimensional, two-temperature model.

Effects of swirl on intermittency characteristics in turbulent non-premixed flames [PDF]

, 2012
Swirl effects on velocity, mixture fraction and temperature intermittency have been analysed for turbulent methane flames using LES. The LES solves the filtered governing equations on a structured Cartesian grid using a finite volume method, with ...

Autoignition and flame propagation in non-premixed MILD combustion [PDF]

Combustion and Flame, 2019
Direct Numerical Simulation (DNS) data of Moderate or Intense Low-oxygen Dilution (MILD) combustion are analysed to gather insights on autoignition and flame propagation in MILD combustion. Unlike in conventional combustion, the chemical reactions occur over a large portion of the computational domain. The presence of ignition and flame propagation and
