Spray-Flame Dynamics in a Rich Droplet Array
We numerically study spray-flame dynamics. The initial state of the spray is schematized by alkane droplets located at the nodes of a face-centered 2D-lattice. The droplets are surrounded by a gaseous mixture of alkane and air. The lattice spacing s reduced by the combustion length scale is large enough to consider that the chemical reaction occurs in a heterogeneous medium. The overall spray e...
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 کاملReconstruction of flame temperature field with Optical Sectioning Method
The temperature information is of great significance to the study of flame structure, soot distribution and combustion mechanism. It is also vital to combustion control. This paper presents the design, implementation and evaluation of a flame imaging system based on optical sectioning method to reconstruct the steady state temperature field of candlelight. A 3-D luminous object can be regarded ...
متن کاملDroplet Transport in a Swirl-Stabilized Spray Flame
Droplet transport processes that occur in fuel sprays and spray flames were examined using laser velocimetry, phase Doppler interferometry, and laser sheet beam photography. Droplet size and velocity (axial and radial) distributions were obtained in a swirl-stabilized, pressure-atomized kerosene spray under nonburning and burning conditions. The results show that the introduction of swirl to th...
متن کاملinvestigation of flame location effect on flame temperature in premixed counterflow combustion of particle-cloud
the premixed counterflow flames propagation in combustion of mixture which is a uniform mixture of fuel particles and air is analytically studied. this analysis framework is based on thermal-diffusion model with assumption that the lewis number is unit and the strain rate is constant. velocity profile is assumed as a function of one variable like x. the structure of the flame is presumed to con...
