عنوان المقالة: Non- Newtonian Hydro-dynamic pressure distribution in a complex geometry coating unit (stepped & converging exponential part) Theoretical Predictions.
Hydrodynamic coating of wires and wire robs is a process, whereby a metal continuum is coated by passing it through a
hydrodynamic pressure unit filled with polymer melt. The geometry of the coating unit is parallel (stepped) in the first section
while becomes converging exponential the second part. Theoretical analysis has been found in literature and applied to predict the
pressure distribution in the complex pressure unit. In this paper a mathematical model has been developed for the pressure
distribution within a complex geometry pressure unit for hydrodynamic coating of wires and wire robs. Theoretical results are
obtained for different continuum speeds in terms of the changes in viscosity, shear stress and pressure distributions within the
unit, such results will help in assessing and evaluating the performance of such coating units
