Combustion Simulation in Afterburner Using Flamelet Model Based on OpenFOAM

A flamelet-based model for supersonic combustion

The renewed interest in high-speed flight has recently demonstrated the need for the development of hypersonic air-breathing propulsion systems, i.e., in which the ambient air is used as oxidizer. These systems have long been recognized as the most well-suited for hypersonic propulsion. Although a traditional ramjet is most appropriate for supersonic speeds (Mach 3 to 5), hypersonic speeds (Mac...

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

Flamelet Analysis of Turbulent Combustion

Three-dimensional direct numerical simulations are performed of turbulent combustion of initially spherical flame kernels. The chemistry is described by a progress variable which is attached to a flamelet library. The influence of flame stretch and curvature on the local mass burning rate is studied and compared to an analytical model. It is found that there is a good agreement between the simu...

Extended flamelet model for LES of non-premixed combustion

A Flamelet Time Scale combustion model for turbulent combustion in KIVA

Most flamelet models for turbulent combustion assume that a turbulent diffusion flame behaves locally as a steady, one-dimensional, laminar, strained flame. While this assumption works well in many practical applications, it fails to take into account finite rate kinetic effects that occur at low Damköhler numbers. It has been shown by Cook et al. (1997) that a steady laminar flamelet model ove...
