Numerical simulation on fluid flow and heat transfer of a brush seal configuration

The fluid flow and heat transfer through a brush seal configuration were numerically simulated. The brush bristles were taken as a porous material and the Darcy law was used instead of the standard momentum equation. For the rest of computational domain, the N-S equations in the original forms were applied. A simple experimental method was proposed to obtain the diffusion coefficient of the Darcy law. A typical calculation reveals that the methodology is simple and effective.
