Abstract
DURING our study of the flow properties of fluids we have observed a ribbed surface on a viscoelastic fluid when it exited from a long, smooth, slit-like flow channel1. Fig. 1 shows an example of this phenomenon as such a fluid leaves the channel. The surface had the appearance of corduroy (cycloidal cross-section) and this unusual flow pattern was remarkably regular and stable.
