AbstractTo describe uncured rubber melt flow, a modified Phan–Thien–Tanner (PTT) model was proposed to characterize the rheological behavior and a viscoelastic one-dimensional flow theory was established in terms of incompressible fluid. The corresponding numerical method was constructed to determine the solution. Rotational rheological experiments were conducted to validate the proposed model. The influence of the parameters in the constitutive model was investigated by comparing the calculated and experimental viscosity to determine the most suitable parameters. The uncured rubber viscosity was 3–4 orders larger than that of plastic and did not have a visible Newtonian region. Compared with the Cross-Williams-Landel-Ferry (Cross-WLF) and original PTT models, the modified PTT model can describe the rheological characteristics in the entire shear-rate region if the parameters are set correctly.

The One

A model is presented to describe the one-dimensional flow of an incompressible fluid through a deformable porous material. The model is based on the Forchheimer extension of the Darcy law for flows through incompressible media, where the Forchheimer coefficients are functions of the local stress. Experiments to determine the stress-dependence of the coefficients for polyurethane foam specimens are described. The coefficients are then used in the model to predict the mass flow rate through long polyurethane specimens as a function of the applied pressure difference across the material. The predictions of the model are compared with experimental observations.

Effective Use

Direct flow induction devices based on pressure exchange are highly efficient and very compact because of the effective use of the non-steady flow and the reversible pressure work on the fluid-fluid interfaces. These technical advantages will broaden their practical applications to such areas as air conditioning, water desalinization and gas turbine cycles etc. The current paper will discuss in detail the concept of pressure exchange. The physical mechanism of pressure exchange is explored by studying a one dimensional shock tube and a simple two-dimensional example by use of the computational analysis. A novel three-dimensional pressure exchange ejector invented by Garris will be introduced.
