Flow Behavior Passing Through a Porous Medium, CFD Approach

Overview of Fluid Flow in Porous Media Simulation

Project Description

Aiming to grasp fluid dynamics via various porosities, this work uses ANSYS Fluent to look at fluid behaviour inside porous media.  Industries include food, oil, textiles, and filtration are common with porous materials.

Methodology

• Geometry and Meshing: The model is made up of an upstream flow domain, a porous medium domain, and a downstream flow domain.  The model, which has a structured mesh of 35,017 components, was created in ANSYS Design Modeller and meshed in ANSYS Meshing.
• Porous Medium Definition: A porosity coefficient defines the porous media; it is the ratio of void space to whole space.  Three porosities—0.5, 0.7, and 0.9—are examined to evaluate their influence on fluid flow.

Conclusion

The simulation findings produce contours of static pressure drop, turbulent viscosity, velocity, and pressure.

• Pressure and Flow Dynamics: A pressure drop is seen as fluid moves through the porous medium, hence verifying the porous material's function in lowering fluid pressure.
• Comparative Analysis: Different porosities show different pressure drops, hence stressing the effect of porosity on fluid behaviour.

This paper shows how porous media change the properties of fluid flow, hence providing ideas for use in many sectors.
