Numerical Simulation of a Laboratory-Scale Turbulent Slot Flame
We present three-dimensional, time-dependent simulations of the flowfield of a laboratory-scale slot burner. The simulations are performed using an adaptive time-dependent low Mach number combustion algorithm based on a second-order projection formulation that conserves both species mass and total enthalpy. The methodology incorporates detailed chemical kinetics and a mixture model for differen...
متن کاملNumerical simulation of a laboratory-scale turbulent V-flame.
We present a three-dimensional, time-dependent simulation of a laboratory-scale rod-stabilized premixed turbulent V-flame. The experimental parameters correspond to a turbulent Reynolds number, Re(t) = 40, and to a Damköhler number, D(a) = 6. The simulations are performed using an adaptive time-dependent low-Mach-number model with detailed chemical kinetics and a mixture model for differential ...
متن کاملNumerical Simulation of a Premixed Turbulent V-Flame
Turbulent premixed combustion is a major active research topic in combustion science. A number of computational studies have focused on idealized configurations to aid in interpreting flame dynamics observed in the laboratory, including one-dimensional strained flames, two-dimensional vortex/flame interactions and limited three-dimensional direct numerical simulations. In this paper, we present...
متن کاملDirect Numerical Simulation of a Turbulent Lifted Flame: Stabilisation Mechanism
A turbulent lifted slot-jet flame is studied using direct numerical simulation (DNS). A single step chemistry model is employed with a mixture-fraction dependent activation energy to quantitatively reproduce the dependence of laminar burning rate on equivalence ratio that is typical of hydrocarbon fuels. It is observed that the leading flame edge exhibits a single branch close to the stoichiome...
متن کاملNumerical Simulation of Skewed Slot Effect on Local Scour Reduction
Local scouring around bridge piers is a natural phenomenon caused by the erosive process of flowing stream on alluvial beds. The 3D flow field around bridge piers interacting with the bed materials increases complexity of local scour process. The local scour depth develops in accelerated flows and if it is not predicted correctly, the bottom level of local scour hole will exceed the original le...
