HYDRODYNAMICS OF A CENTRIFUGAL NONLINEAR-VISCOELASTIC LIQUID FILM

Film fl ow of nonlinear-viscoelastic fl uid over the surface of a rotating curvilinear extension piece has been considered with account for the lag. The rheological model used is that of White–Metzner. The problem has been solved by the method of integral relations with the use of the von Karman (κ = 0) and Leibenson (κ = 1) approximations. Two algebraic equations with two unknowns have been obtained realized by the method of iterations. Experimental data are given.
