This paper presents one-dimensional simulations of combustion of an air/methane mixture in porous materials using a model that explicitly considers the intra-pore levels of turbulent kinetic energy. Transport equations are written in their time-and-volume-averaged form and a volume-based statistical turbulence model is applied to simulate turbulence generation due to the porous matrix. Four different thermomechanical models are compared, namely Laminar, Laminar with Radiation Transport, Turbulent, Turbulent with Radiation Transport. Combustion is modeled via a unique simple closure. Preliminary testing results indicate that a substantially different temperature distribution is obtained depending on the model used. In addition, for high excess air peak gas temperature is reduced and the flame front moves towards the exit of the burner. Also, increasing the inlet flow rate for stoichiometric mixture pushes the flame out of the porous material.

## Abstract The conversion of methane to hydrogen by partial oxidation in a porous media reactor was investigated over a range of large fuelβ air equivalence by numerical simulation. A oneβdimensional twoβtemperature model was presented and the detailed GRI 1.2 mechanism was used for methane oxidat
Several results using numerical experimentation on homogeneous three-dimensional turbulent MHD flows are reviewed. The role (or absence thereof) of chaos and that of kinetic helicity for the kinematic dynamo problem is described. A second topic concerns the formation of large scale coherent structur
