Rheometry towards complex flows: Squeeze flow technique

Makromolekulare Chemie. Macromolecular Symposia, 1992
AbstractDisk‐like samples are submitted to controlled squeezing forces between parallel plates and the time‐dependent sample height is measured. Isothermal tests at constant force enable the determination of viscosity functions of melts. Experiments using a constant disk radius and a constant disk volume are compared. Creep and creep recovery tests are

Squeezing flow between parallel plates

Wear, 1977
Abstract A similarity solution for the full Navier-Stokes equations is presented for the unsteady flow between two plates approaching or receding from each other symmetrically. The similarity solution exists when the distance between the plates varies as the square root of a linear function of time.

A new instrument for dynamic helical squeeze flow which superposes oscillatory shear and oscillatory squeeze flow

Review of Scientific Instruments, 2012
Simple shear flow has been widely used as a model flow system to investigate the rheological properties of complex fluids. Although it is useful and easy to apply, the shear flow is too simple compared with the complicated flows encountered in real processes.

Squeeze Flow Measurements in Mechanical Heart Valves

ASAIO Journal, 2008
High-speed squeeze flow during mechanical valve closure is often thought to cause cavitation, either between the leaflet tip and flat contact area in the valve housing, seating lip, or strut flat seat stop, depending on design. These sites have been difficult to measure within the housing, limiting earlier research to study of squeeze flow outside the ...

Squeezing flows of polymeric liquids

AIChE Journal, 1978
AbstractAn experimental study has been done on the flow of viscoelastic liquids squeezed between two flat parallel plates. In fast squeezes under a constant load, the plates did not come together as rapidly as predicted by inelastic fluid theory. Our experimental data suggest that this device is not generally useful as a viscometer.

Squeezed flow preconcentration for probe tip biosensors

Analytical Biochemistry, 2014
The preconcentration of analytes improves sensing using probe tips. In this work, we report a method based on creating a squeeze flow between a cylinder and circular coverslip to preconcentrate material at the liquid-gas interface while allowing a probe tip to be readily inserted there.

Squeezing Flows of Viscoelastic Liquids

1980
Squeezing flows occur in a variety of industrial applications, including lubrication, printing, and sheet molding. Squeezing flow also occurs in the region between two bubbles growing in a foaming liquid. An experiment designed to study squeezing flow has been designed, and data indicate that the force-time behavior cannot be modeled using purely ...

Squeeze flow in thermoplastic composites

1999
In order to permanently alter the shape of a thermoplastic composite, without degrading its material properties, it is necessary to heat the polymer matrix prior to forming. Crystalline and semicrystalline polymers must be completely melted to allow the long polymer chains to slide past one another.
