An analysis for describing a tubular membrane expansion under vacuum in a batch air separator is presented. Assuming that the polymer material properties obey an Oldroyd's Fluid B, the effect of rheological properties, relaxation parameters, and surface tension on the membrane inflation are investigated. Numerical results indicate that a viscoelastic membrane with a small Deborah number shortens the transition period of deformation and the magnitude of expansion.
