A-priori and a-posteriori studies of a direct moment closure approach for turbulent combustion using DNS data of a premixed flame

Autor: Antonio Attili, Runzhi Liu, Yun Bai, Kun Luo, Jianren Fan, Heinz Pitsch, Fabrizio Bisetti

Publikováno v: Proceedings of the Combustion Institute. 38:3003-3011

The direct moment closure (DMC) approach for modeling the filtered chemical source terms in large eddy simulation of turbulent combustion is comprehensively assessed by using direct numerical simulation data of a turbulent premixed flame with a skele

Evolution and scaling of the peak flame surface density in spherical turbulent premixed flames subjected to decaying isotropic turbulence

Autor: Tejas Kulkarni, Fabrizio Bisetti

Publikováno v: Proceedings of the Combustion Institute. 38:2817-2824

The peak flame surface density within the turbulent flame brush is central to turbulent premixed combustion models in the flamelet regime. This work investigates the evolution of the peak surface density in spherically expanding turbulent premixed fl

P-DRGEP: a novel methodology for the reduction of kinetics mechanisms for plasma-assisted combustion applications

Autor: Nicholas E. Deak, Perrine Pepiot, Fabrizio Bisetti, Nicholas Kincaid, Aurélie Bellemans

Publikováno v: Proceedings of the Combustion Institute

Detailed kinetics mechanisms for plasma-assisted combustion contain numerous species and reactions that model the interplay between non-equilibrium plasma processes and hydrocarbon oxidation. While physically accurate and comprehensive, such detailed

Surface morphology and inner fractal cutoff scale of spherical turbulent premixed flames in decaying isotropic turbulence

Autor: Fabrizio Bisetti, Tejas Kulkarni

Publikováno v: Proceedings of the Combustion Institute. 38:2861-2868

The surface of turbulent premixed flames is fractal within a finite range of scales and the fractal dimension and inner cutoff scale are key components of fractal turbulent combustion closures. In such closures, the estimate for the surface area is s

Plasma-assisted ignition of methane/air and ethylene/air mixtures: Efficiency at low and high pressures

Autor: Aurélie Bellemans, Fabrizio Bisetti, Nicholas E. Deak

Publikováno v: Proceedings of the Combustion Institute. 38:6551-6558

The ignition of methane/air and ethylene/air mixtures by nanosecond pulsed discharges (NSPD) is investigated numerically using a zero-dimensional isochoric adiabatic reactor. A combustion kinetics model is coupled with a non-equilibrium plasma mechan

Chance-Constrained Stochastic Optimal Control via Path Integral and Finite Difference Methods

Autor: Apurva Patil, Alfredo Duarte, Aislinn Smith, Fabrizio Bisetti, Takashi Tanaka

This paper addresses a continuous-time continuous-space chance-constrained stochastic optimal control (SOC) problem via a Hamilton-Jacobi-Bellman (HJB) partial differential equation (PDE). Through Lagrangian relaxation, we convert the chance-constrai

Flamelet chemistry model for efficient axisymmetric counterflow flame simulations with realistic nozzle geometries and gravitational body force

Autor: Evrim Solmaz, Fabrizio Bisetti

Publikováno v: Combustion Theory and Modelling. 24:926-952

A flamelet model is applied to the simulation of axisymmetric counterflow laminar flames including gravitational acceleration and the geometrical details of main nozzles and annular shrouds. The fl...
