Sounding Solid Combustibles: Non-Premixed Flame Sound Synthesis for Different Solid Combustibles

IEEE Transactions on Visualization and Computer Graphics, 2018
With the rapidly growing VR industry, in recent years, more and more attention has been paid for fire sound synthesis. However, previous methods usually ignore the influences of the different solid combustibles, leading to unrealistic sounding results.

Study of non – Premixed combustion of propane and methane using CFD

Materials Today: Proceedings, 2021
Abstract The combustion of the fuel inside a combustor is a complicate chemical phenomena where conversion of chemical energy of the species into the heat energy takes place by burning in the presence of oxygen but in case of the incomplete combustion the unburnt hydrocarbons are evolved as the emissions from the combustors which effects the ...

The Flamelet Model for Non-Premixed Combustion

2011
The flamelet approach for non-premixed combustion is based on the description of the turbulent flame as a collection of laminar flame elements embedded in a turbulent flow and interacting with it. The local structure of the flame at each point of the flame front is supposed to be similar to a laminar flamelet, while the interaction with turbulence is ...

A Distributed Transfer Function for Non-Premixed Combustion Oscillations

Combustion Science and Technology, 2012
The present study discusses a general distributed transfer function for non-premixed flames based on conservation equations. Also, a distributed transfer function for idealized, two-dimensional, flat, non-premixed flames is calculated using Green's function method.

An unsteady laminar flamelet model for non-premixed combustion

Combustion Theory and Modelling, 2000
While it is widely recognized that unsteady effects are important in turbulent diffusion flames, few simple models take unsteadiness into account. We show that this can be done with a laminar flamelet model based on steady strained flamelet libraries.

Explicit Filtering LES for Turbulent Non-Premixed Combustion

Volume 1: Symposia, Parts A and B, 2007
Two models for large eddy simulation of turbulent reacting flow in homogeneous turbulence were studied. The sub-grid stress arising out of non-linearities of the Navier-Stokes equations were modeled using an explicit filtering approach. A filtered mass density function (FMDF) approach was used for closure of the sub-grid scalar fluctuations.

Mass transfer and combustion in transcritical non-premixed counterflows

Combustion Theory and Modelling, 2009
The problem of transcritical mass transfer and combustion is considered in the counterflow geometry established at ambient pressures exceeding the critical pressure of the fluids but for an injection temperature (or injection temperatures) below critical.

Progress in Numerical Modeling of Non-Premixed Combustion

2014
Progress is made on the numerical modeling of both laminar and turbulent non-premixed flames. Instead of solving the transport equations for the numerous species involved in the combustion process, the present study proposes reduced-order combustion models based on local flame structures.

DNS of non-premixed combustion in a compressible mixing layer

2001
The non-premixed reaction of fuel with air in a mixing layer is studied using DNS. The situation is a model for the mixing-controlled combustion in a Diesel engine. We show that the combustion region can be comparably passive with respect to relatively large scale aerodynamic instabilities.

Combustion of Hydrocarbon and Alternative Fuels in Non-premixed Flows

2021
In this diploma thesis, selected aspects of the combustion of hydrocarbon fuels and alternative fuels, more precisely pure ethanol, mixtures of ethanol with decane, and pure decane, are investigated experimentally in non-premixed flows. The critical conditions of autoignition and extinction are examined more closely for these fuels.
