Abstract
A study has been done on the three dimensional turbulent flow characteristic near the porous wall. The porous holes are considered by penetrating the wall in regular arrangement, and porosity is controlled by diameter of holes. Flow characteristics near the three dimensional porous wall are compared with field test results and self-generated experimental results. FLUENT is employed for computational analysis on the effect of three dimensional porosity with flow and pressure characteristics. As a result, drag coefficient is defined and compared for three dimensional effect. The drag coefficient is mostly a function of porosity, whereas the effect of Reynolds number is minimal, and its correlation is presented in terms of three dimensional porosity.
