Parallel plate viscometer
WebApr 15, 2024 · A parallel plate viscometer is an experimental device that can measure the viscosity of glass using PPV. This is done by determining the rate of change in the thickness of a cylindrical specimen between parallel plates moving perpendicular to their common central axis, as depicted in Fig. 1 [ 17 ]. WebParallel Plate Viscometry (PPV) PPV is a useful test to investigate glass viscosities within the range of 10 4 Pas to 10 8 Pas, as well as measuring the softening point of the glass. To perform this test, the experimental device referred to as a parallel plate viscometer determines any change in the thickness of a cylindrical specimen through ...

WebAbstract Rotational viscometry is usually used to measure the properties of fluids in flows which approximate a simple shearing motion (Fig. 9.l). 1–4 Such a flow can be effected in a fluid contained between two infinite parallel plates by fixing one and moving the second parallel to the first at a fixed speed. WebDec 1, 2003 · The fluid dynamics of parallel plates viscometer is investigated mathematically using both the Navier-Stokes and continuity equations for an incompressible viscous fluid. The problem admits similarity solutions, thereby reducing the unsteady Navier-Stokes equations to a parameter dependent fourth order nonlinear ordinary differential …
