Which phenomenon primarily dictates the increased drag coefficient of non-spherical airborne particles over spherical particles of equivalent volume?

💡 Explanation

When particle shape deviates from spherical, boundary layer separation occurs because air flows over a non-aerodynamic shape, creating turbulent eddies causing pressure drag and increasing drag coefficient. Therefore flow separation results, rather than intermolecular forces or energy resonance which operate on molecular scales with minimal macroscopic effects on drag.
