Filtered density functions from direct numerical simulation of a reactive jet in cross-flow

, 2010
Direct numerical simulation (DNS) with multi-step hydrogen-air chemical kinetics is used to investigate the nearfield of a flame stabilized above a reactive jet in cross-flow (JICF). JICF configurations are typically used where rapid mixing is desirable;

DNS of turbulence backscatter in a laboratory-scale swirl stabilized aero-combustor

Applications in Energy and Combustion Science
Classical theories of turbulence suggest that the kinetic energy cascade in nonreacting flows has a net transfer of energy from large to small scales. However, previous studies demonstrated that the thermal expansion of premixed flames can reverse the ...

Simulations of combustion roar in turbulent attached and lifted turbulent methane jet flames

Engineering Transactions, 2014
The present work presents sample results of preliminary computations of the turbulent aerothermodynamic flow field and of the noise generated by the flame front, due to turbulent fluctuations in the flame (combustion roar), in lifted and attached jet ...

Numerical modelling of a CAN combustion chamber with swirler using probability density functions (PDF) and eddy dissipation model (EDM)

Results in Engineering
This study employs a well-established experimental setup, involving a can combustor with swirling, recirculating, and turbulent reactive flow to evaluate the performance of combustion and turbulence modelling within the combustion chamber.
