A numerical investigation of the fluid mechanical sewing machine
P.-T. Brun, N.M. Ribe, B. Audoly
A new numerical algorithm is used to simulate the variety of patterns generated by a thin thread of viscous fluid falling on a surface. The discrete viscous thread (DVT) method proves successful in simulating a range of interesting configurations when compared to experimental results previously seen in the laboratory. The simulations of the viscous sewing machine reveals unique patterns that were characterized using a new identification method that computes the Fourier spectra of the longitudinal and transverse components of the motion of the thread’s contact point with the belt.
