Numerical Investigation of Fluid Flow Past a Cylinder: Effect of Surface Roughness

Puntos clave

The aim is to explore how varying surface roughness affects fluid flow around a cylinder.
Used direct numerical simulation (DNS) for analysis.
Applied the Cartesian cut-cell method for geometrical representation.
Implemented quadtree adaptive mesh refinement for improved accuracy.
Identified distinct changes in flow patterns based on surface roughness.
Observed variations in drag force related to roughness levels.

Resumen

This study employs direct numerical simulation (DNS), combined with the Cartesian cut-cell method and quadtree adaptive mesh refinement, to systematically investigate the effects of surface roughness on the flow past a cylinder. The varying surface roughness is described mainly in terms of the wavenumber
