Computations of Turbulent Evaporating Sprays
A computational study of turbulent evaporating sprays is reported. The major focus is to study the structure of turbulent evaporating sprays and to examine the sensitivity of their vaporization behavior to transient liquid-phase processes. Three models considered to represent these processes are the thin-skin, infinite-diffusion, and diffusionlimit models. Favre-averaged equations with a k-s-g ...
متن کاملRadiation modeling of a turbulent diffusion flame in diesel engine
The purpose of this study is to investigate the effect of radiation heat transfer on temperature distribution and heat flux to the walls of a diesel engine. A diffusion flame is modeled in a simple cylindrical geometry and boundary conditions are defined. A specific solver which can model the turbulent diffusion flame by considering radiation in participating media is used to solve the problem....
متن کاملFlame length measurements of the turbulent plume
A steady source of buoyancy creates a plume. Experi mental and theoretical studies of plumes have been mainly concerned with the far-field (self-similar) velocity and den sity profiles. •-3 Yet in many practical situations, knowledge regarding the rate of molecular scale mixing of the buoyant fluid with its environment is needed. This is especially true in the context of atmospheric studies, ...
متن کاملDirect Numerical Simulation of Sprays: Turbulent Dispersion, Evaporation and Combustion
Numerical procedures to describe the dispersion, evaporation and combustion of a polydisperse liquid fuel in a turbulent oxidizer are presented. Direct Numerical Simulation (DNS) allows one to describe accurately the evolution of the fully compressible gas-phase coupled with a Lagrangian description in order to describe two-phase flows. Standard coupling is used for the Eulerian/Lagrangian syst...
متن کاملApplication of a Flame Dictionary Method in Turbulent Premixed Flame Modeling. Construction of a Flame Dictionary
|The construction of a ame dictionary of ame speeds and preheat thicknesses for a given reaction will be discussed. Once the entries of the dictionary have been established, they can be accessed by researchers and programmers to be used in diierent combustion applications. An application of the ame dictionary for turbulent combustion in a circular cylinder is given. Chemical reactions are often...
