Numerical solutions of a two-dimensional isothermal problem 
of flow of a relaxing fluid between two rotating cylindrical surfaces 
have been constructed. All the results have been obtained by solution 
of a complete system of hydrodynamic equations. The influence of the 
internal relaxation time on the carrying capacity of a lubricating 
film and the flow structure has been analyzed.
