Numerical Investigation of Vortex Interaction in Pipe Flow
To discover the nonlinear characteristics of pipe flow, we simulated the flow as a sum of many vortex rings. As a first step, we investigated the nonlinear interaction among a maximum of three vortex rings. The pipe wall was replaced by many bound vortices. A free vortex ring moves right or left according to the radius, and that of a particular radius keeps the initial position. The energy of a...
متن کاملNitric Oxide Formation during Flame/vortex Interaction
The formation of nitric oxide was investigated in methane diffusion flames under the perturbation of laminar vortices. Laser-induced fluorescence and Raman spectroscopy were used to measure nitric oxide, major species, and temperature, and to obtain the time evolution of the scalar dissipation rate at the stoichiometric surface during the flame/vortex interaction. Vortices with two characterist...
متن کاملNumerical investigation of plasma / flame interactions
Flame ignition or extinction is the result of very complex interactions between combustion chemistry and turbulence. It has been recently observed in experimental studies [1,2] that the presence of a plasma discharge in the vicinity of reaction zones affects combustion. For instance, a discharge generated in a combustion chamber produces a pool of radicals. These highly reactive species strongl...
متن کاملAnalysis of carbon chemistry in numerical simulations of vortex flame interaction
Recent progress in simulation methodologies and new, high-performance parallel architectures have made it is possible to perform detailed simulations of time-dependent multidimensional combustion phenomena using comprehensive kinetics mechanisms. However, as simulation complexity increases, it becomes more difficult to extract meaningful quantitative information about the flame from the numeric...
متن کاملSoot topography in a planar diffusion flame wrapped by a line vortex
An experimental study of the interaction of a planar diffusion flame with a line vortex is presented. A planar diffusion flame is established between two coflowing, equal velocity streams of acetylene diluted with nitrogen and air. A line vortex is generated on demand by momentarily pulsing one of the flow streams by way of electromagnetic actuation of a piston in the flow apparatus. The flame–...
