A Comparison of Strategies for Direct Numerical Simulation of Turbulence Chemistry Interaction in Generic Planar Turbulent Premixed Flames
Abstract Three different methods to introduce turbulence in the computational domain of Direct Numerical Simulations (DNS) of statistically planar turbulent premixed flame configurations have been reviewed and their advantages and disadvantages in terms of run time, natural flame development, contro...

It has been found that there is no method, which is clearly superior to the other two alternative methods. An analysis has been performed to explain why Lundgren’s physical space linear forcing results in an integral length scale which is, independent of the Reynolds number, a constant fraction of the domain size. Furthermore, an evolution equation for the integral length scale has been derived, and a scaling analysis of its terms has been performed to explain the evolution of the integral length scale in the context of Lundgren’s physical space linear forcing. Finally, a modification to Lundgren’s forcing approach has been suggested which ensures that the integral length scale settles to a predetermined value so that DNS of statistically planar turbulent premixed flames with physical space forcing can be conducted for prescribed values of Damköhler and Karlovitz numbers. | ||

An analysis has been performed to explain why Lundgren’s physical space linear forcing results in an integral length scale which is, independent of the Reynolds number, a constant fraction of the domain size. Furthermore, an evolution equation for the integral length scale has been derived, and a scaling analysis of its terms has been performed to explain the evolution of the integral length scale in the context of Lundgren’s physical space linear forcing. Finally, a modification to Lundgren’s forcing approach has been suggested which ensures that the integral length scale settles to a predetermined value so that DNS of statistically planar turbulent premixed flames with physical space forcing can be conducted for prescribed values of Damköhler and Karlovitz numbers.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Turbulent premixed combustion</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Statistically planar flame</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Turbulent forcing</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Turbulent inflow</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Chakraborty, Nilanjan</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ketterl, Sebastian</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Flow, turbulence and combustion</subfield><subfield code="d">Springer Netherlands, 1998</subfield><subfield code="g">99(2017), 3-4 vom: 11.

A Comparison of Strategies for Direct Numerical Simulation of Turbulence Chemistry Interaction in Generic Planar Turbulent Premixed Flames |
abstract |
Abstract Three different methods to introduce turbulence in the computational domain of Direct Numerical Simulations (DNS) of statistically planar turbulent premixed flame configurations have been reviewed and their advantages and disadvantages in terms of run time, natural flame development, control of turbulence parameters and convergence of statistics extracted from the simulations have been discussed in detail. It has been found that there is no method, which is clearly superior to the other two alternative methods. An analysis has been performed to explain why Lundgren’s physical space linear forcing results in an integral length scale which is, independent of the Reynolds number, a constant fraction of the domain size. Furthermore, an evolution equation for the integral length scale has been derived, and a scaling analysis of its terms has been performed to explain the evolution of the integral length scale in the context of Lundgren’s physical space linear forcing. Finally, a modification to Lundgren’s forcing approach has been suggested which ensures that the integral length scale settles to a predetermined value so that DNS of statistically planar turbulent premixed flames with physical space forcing can be conducted for prescribed values of Damköhler and Karlovitz numbers. © Springer Science+Business Media B.V. 2017 |
