Numerical Investigation of Drag Force on Permeable Fixed Bed

Key Points

• The aim is to explore the drag force in permeable fixed beds and its impact on fluid dynamics.
• Coupled analysis using individual element method and fluid computation technique
• Application of fluid dynamics models to calculate interaction forces between sediment and fluid
• Investigation of pressure loss in homogeneous porous media
• Identified challenges in applying fluid drag models to rapidly changing flow conditions
• Demonstrated the need for further exploration of drag force in mobile bed surfaces
