We have investigated the stability of the curved patterns formed by the continuous deposition of a liquid thread on a moving substrate with Newtonian and non-Newtonian fluids. Effects of different parameters such as capillary number, ratio of average inlet velocity of the fluid to the velocity of the substrate, contact angle and the radius of deposition have been studied on the deposition of the liquid thread. Variation of velocity of the contact lines and the width of the liquid thread are observed subject to different parameters. The results show the effect of fluid properties and fluid solid interaction such as surface tension effect, contact angle and wettability of the substrate on the final pattern made by the Newtonian and non-Newtonian liquid thread deposited on a rotating substrate.
