Drag coefficient for irregularly shaped grains: rotational dependence at high Reynolds numbers
Álvaro Vergara, Deheng Wei, Raúl Fuentes
The nature and behaviour of the drag coefficient of irregularly shaped grains within a wide range of Reynolds numbers is discussed. Using computational fluid dynamics (CFD) tools,…
