On the Coupling Between Length and Time Scales in Reactive Flows
نویسندگان
چکیده
We discuss one-dimensional steady laminar premixed flames in a mixture of calorically imperfect ideal gases described by detailed kinetics and multi-component transport. The required spatial discretization to capture all detailed continuum physics in the reaction zone is determined a posteriori and estimated a priori. Application of the method to laminar premixed flames in several mixtures over a wide range of pressures and fuel–air ratios reveals that the finest length scale is on the order of 10 cm.

Effects of coupling on turbulent gas-particle boundary layer flows at borderline volume fractions using kinetic theory
This study is concerned with the prediction of particles’ velocity in a dilute turbulent gas-solidboundary layer flow using a fully Eulerian two-fluid model. The closures required for equationsdescribing the particulate phase are derived from the kinetic theory of granular flows. Gas phaseturbulence is modeled by one-equation model and solid phase turbulence by MLH theory. Resultsof one-way and...

متن کاملDiffusion Effects on Slow Invariant Manifolds
Diffusion effects on the Slow Invariant Manifold (SIM) of a closed reactive system are examined with the goal of developing a model reduction technique which rigorously accounts for the coupling of reaction and diffusion processes. A robust method of constructing a one-dimensional SIM by calculating equilibria and then integrating heteroclinic orbits is extended to systems with diffusion across...
متن کاملNumerical Investigation on Contaminant Dispersion from a Source over the Blocks in Steady and Unsteady Flows
This paper deals with numerical study of semi-finite incompressible flow of air over two blocks with different heights in the presence of a condensing-source, dispensing- contaminant in the flow, in both steady and unsteady states. The numerical solution of governing PDE equations are constructed by a finite-volume method applied on structured grid arrangement. The effects of air flow velocity,...
متن کاملEstimation of salinity, heat and buoyancy budgets of the inflow coastal current into the Persian Gulf from the Strait of Hormuz
An analytical model for a coastal boundary current was used to investigate heat and salt budget of exchange flows in the Persian Gulf as a marginal sea. Coastal boundary currents exchange heat and freshwater with the mosphere and the offshore waters. As heat and salinity fluxes caused by air-sea interaction and eddy activities, different temperature and salinity associated with boundary current...
