چکیده
Ogston & Stanier (1950, 1951, 1952) have referred to measurements made with a Couette viscosimeter. Since this viscosimeter can be constructed almost wholly in an ordinary laboratory workshop, and since it has proved to be convenient and accurate in CONSTRUCTION Drive. A type RQ synchronous motor, 73 rev./ min. (Drayton Regulator and IIistrument Co. Ltd.) is coupled by a stirrup coupling to the plate of a

Taylor instabilities in colloidal crystals
2014 Recently we have developed a Couette viscosimeter for studying the shearing of colloidal crystals. We report here that with increasing shear rate the colloidal crystal melts (for 03C9crit) and above a critical shear rate, 03C9T0, Taylor instabilities develop. After stopping the shearing flow the suspension recrystallizes in a special texture which preserves the pattern of the Taylor rolls....
متن کاملDrag Reducing Polymers in Vascular System: Viscosity Measurement and Polymers Types and Concentrations
Toms (1949) discovered that if a very small amount of drag reducing polymers (DRP) are added in the flow, approximately 10 ppm by weight or less, a substancial reduction in pressure drop at a given flow rate resulted. Then, since 1948, the phenomenon of drag reduction have been studied by many researchers with the objective of understand the drag reduction mechanism. In the last decades, the dr...
متن کاملEntropy generation due to unsteady hydromagnetic Couette flow and heat transfer with asymmetric convective cooling in a rotating system
Entropy generation in an unsteady hydromagnetic Couette flow of a viscous incompressible electrically conducting fluid between two infinite horizontal parallel plates in a rotating system have been analyzed. Both the lower and upper plates of the channel are subjected to asymmetric convective heat exchange with the ambient following the Newton's law of cooling. A numerical solution for governin...
متن کاملUsing Burnett Equations to Derive an Analytical Solution to Pressure-Driven Gas Flow and Heat Transfer in Micro-Couette Flow
The aim of the present study is deriving an analytical solution to incompressible thermal flow in a micro-Couette geometry in the presence of a pressure gradient using Burnett equations with first- and second-order slip boundary conditions. The lower plate of the micro-Couette structure is stationary, whereas the upper plate moves at a constant velocity. Non-dimensional axial velocity and tempe...
متن کاملUnsteady free convection oscillatory couette flow through a variable porous medium with concentration profile
In this paper we have studied the effect of free convection on the heat transfer and flow through variable porous medium which is bounded by two vertical parallel porous plates. In this study it is assume that free stream velocity oscillates with time about a constant mean. Periodic temperature is considered in the moving plate. Effect of different parameters on mean flow velocity, Transient ve...
