Development of a Multiphase Flamelet Generated Manifold for Spray Combustion Simulations
Journal of Engineering For Gas Turbines and Power, 2020In this study, a model flame of quasi-one-dimensional (1D) counterflow spray flame has been developed. The two-dimensional (2D) multiphase convection-diffusion-reaction equations have been simplified to one dimension using similarity reduction under ...

The growth of combustion processes along the years was driven both by scientific and technical developments providing disruptive innovations and by the market requirements )(e.g., the development of HVOF spraying by Browning in 1983 was pushed forward by the need to produce WC-Co cermet coatings with superior properties).

Nozzle Spraying Model of Combustion Thermal Spray
Advanced Materials Research, 2013The flame used in combustion flame spraying is typical of a high-temperature free jet. The flow fields of free jets are multi-phase flows that couple the mass and heat transfer. The analytical and numerical solutions to turbulent flows are engineering approximations. This work uses Prandtle’s mixing-length theory to describe the flame spreading of free

Heat Transfer and Fluids Engineering, 1995
Abstract A survey is presented of the most recent developments in the field of spray combustion. During the process of atomization, the breakup of the liquid results in unsteadiness and formation of drop clusters. Mathematical models address the dynamics and evaporation of clusters of monodisperse, uniformly distributed drops embedded ...

Spray Combustion and Atomization
The Physics of Fluids, 1958A statistical formalism for describing the behavior of sprays is presented, which includes the effects of droplet growth, the formation of new droplets, collisions, and aerodynamic forces. Criteria for the efficiency of impinging jet atomization are developed. It is shown that if the incident jets have a size distribution of a generalized Rosin-Rammler

Combustion and Flame, 1959
Abstract The coupled steady-state equations of motion of a statistical ensemble of spherical droplets and a coexisting multicomponent reacting gaseous continuum are derived under the assumption that the induced random fluctuations in the properties of the fluid are negligible.

Symposium (International) on Combustion, 1996
Aspects of interphase transport and multiphase flow relevant to spray combustion are reviewed, considering the structure of the near-injector (dense-spray) region, drop breakup, drop/turbulence interactions and interphase drop transport. Existing measurements of dense-spray structure shown that the dispersedflow flow region is surprisingly dilute, that

Turbulent Spray Combustion Modeling Using Various Kinetic Solvers and Turbulence Models
Journal of Engineering For Gas Turbines and Power, 2018Turbulent spray combustion of n-dodecane was modeled at relevant engine conditions using two combustion models (direct integration of chemistry (DIC) and flamelet generated manifolds (FGM)) and multifidelity turbulence models (dynamic structure large ...

Symposium (International) on Combustion, 1985
Most fuel sprays do not burn or evaporate as individual droplets but as a group. Based on previous studies it is shown that the transition from single droplet to group combustion depends on a single parameter ∈. In the limiting case ∈≪1, which corresponds to most spray parameters of practical interest, evaporation of the fuel occurs in a thin sheath or
