Semi-solid aluminium alloy processing (SSM) has advanced into a more mature process with many applications. The current paper aims to investigate the in-process behaviour of production slurry using an engineering approach estimate properties. A method assess rheological properties semi-solid metal was tested and found capable producing meaningful measurements. foundations this were use Rushton ...

In order to measure the extensional rheological properties of yield stress fluids, we developed a rheometrical approach based on analysis deformations fluid extrudate flowing downward and breaking in successive elongated drops due gravity. Assuming gradients longitudinal velocity radial planes are negligible, local instantaneous strain rate is deduced from variations filament diameter each cros...

Oral mucoadhesive dosage formulations reveal numerous advantages they offer, like easy application, discrete handling and no need to swallow the drug product. Nevertheless, in order ensure correct performance of these preparations, must show suitable physicochemical properties, such as sorption wetting, viscosity adhesion mucous membrane. In this study, properties selected polymers their blends...

(i) A study of the fluids in simple flow situations, such as those found in Rheometry. (ii) The construction of suitable constitutive equations for the non-Newtonian fluids under test. (iii) The use of these constitutive equations in the prediction of behavior in complex flows of practical importance. (iv) An experimental study of the behavior of non-Newtonian fluids in the complexflow situatio...

In this paper, a review of different techniques used to measure the slip length on superhydrophobic surfaces with large slip length is presented. First, we present the theoretical models used to calculate the effective slip length on superhydrophobic surfaces in different configurations of liquid flow. Then, we present the different techniques used to measure the slip past these superhydrophobi...
