WebIf the cylinder's aspect ratio is very long then, yes, the drag should be very similar because the air inside the cylinder is essentially trapped, travels with the cylinder and therefore creates a virtual base to seal the ends of the cylinder. But for stubbier cylinders (think a hula hoop) the hollow one will have different drag.

WebThe normalized aspect ratio varies from approaching zero for a very elongated particle, such as a grain in a cold-worked metal, to near unity for an equiaxed grain.
