A key role in the theory of fiber spinning is played by hydrodynamic models described by nonlinear boundary layer problems. The report examines such boundary value problems using modern methods of functional analysis, hydrodynamics and computational mathematics. An analytical method for constructing solutions in one-dimensional stationary models with boundary conditions has been developed. A numerical method is proposed whose relative errors in determining the characteristics of the heat flow for a flat plate do not depend on the Reynolds number. Theorems on the existence of solutions to boundary value problems arising in physical and technical models of polymers are proven using the Cauchy-Kovalevskaya theorem and the Schauder fixed point principle. Using general existence theorems for solutions of nonlinear equations with a vector parameter, the existence of solutions to a boundary-value problem from boundary layer theory on an unbounded half-interval is proven. The report is intended for specialists in the field of industrial mathematics, its applications in chemical technology, in the theory of materials, as well as scientists and engineers interested in nonlinear boundary value problems.
