Implication

Numerical analysis reveals drag reduction by 21% in spherical particles with surface roughness in laminar flow, indicating the role of irregular surfaces.

Key Points

Drag coefficient drops quadratically with increasing surface roughness, enhancing drag reduction.
Relative roughness is shown to reduce total drag on the particle by over 21% across Reynolds numbers 2 to 8.
The study utilized a 3D Weaire–Phelan model to quantify surface texture and its impact on drag.
Findings may enhance understanding of transport phenomena in engineering applications involving low Reynolds number flows.
