Resumen:
In this work a method of straight lines for a Bingham problem in
cylindrical geometry is developed. A Bingham fluid has viscosity
properties that produce a separation into two regions, a rigid zone and a
viscous zone. We propose a method of lines with the time as a
discrete variable. We prove that the method is well defined for all
times, a monotone property, qualitative behaviours of the solution,
and a convergence theorem. A numerical calculation is included to
illustrate the theoretical results.
