abstract = "Combustion simulations involve the modeling of chemical kinetics,
and due to the complexity of detailed mechanisms, chemistry
reduction techniques are necessary. One model reduction strategy
is the reaction-diffusion manifold (REDIM) method, and to obtain
the REDIM, an evolution equation must be solved till its
stationary solution and a gradient estimation is needed, provided
e.g. from flamelet solutions with detailed chemistry. In this
work, the REDIM technique is applied to simulate methane/air
turbulent flames based on a simplified gradient estimation. This
strategy uses less information in constructing the REDIM,
increasing computational efficiency while reducing computational
costs. Validation is performed for non-premixed laminar flames. A
RANS/transported-PDF framework for the simulation of turbulent
reacting flows is presented and used to validate the proposed
model. Results show that the simplified gradient estimation is
enough to simulate turbulent flames at moderate Reynolds number,
which demonstrates the suitability of REDIM as reduced kinetic
model in reactive flows.",
