Incompressible Turbulent Reattaching Shear Layer Flow Over a Backward Facing Step with Orthotropic Porous Floor Segments

ABSTRACT
The incompressible turbulent reattaching flow over a 2-D backward facing step with different length porous floor segments was investigated numerically. The flow field was solved using the finite element numerical method and the RNG turbulence model. The porous segment can be used to model solid fuel being entrained by the incoming flow in a combustor. The effect of the porous segment length, depth, and anisotropic and orthotropic pressure loss coefficient on the normalized reattachment length (Xr), normalized maximum recirculation velocity (Urec), and normalized maximum turbulent kinetic energy (TKE) are reported and discussed. Depending on the combination of segment length, depth, pressure loss coefficient, and orthotropicity, a floor with porous segments can be used to change the location and magnitude Xr, Urec, and TKE.
