Rheological measurements are quite relevant in the food industry as a tool for physical characterization of raw material prior to processing, for intermediate products during manufacturing, and for finished foods. There are several approaches to conduct these rheological characterizations, and the selected technique pretty much depend on the specific product and the functional characteristics i...

ISBN 952-91-6585-4 (paperback) ISBN 952-10-1476-8 (PDF) The main purpose of the present study was to gain understanding about the rheological (elastic, viscoelastic and viscous) properties of pharmaceutical creams containing sorbitan fatty acid ester surfactants (sorbitan monola...

The paper reviews recent experimental results concerning a wide variety of magnetic nanofluids with high saturation magnetization. Magnetic, rheological and magneto-rheological properties are presented and discussed, especially related to nanostructural processes and colloidal stability in applied magnetic field.

Consideration of sludge rheology is very important for a proper solids transport and to obtain the necessary settler capacity. Although a true yield stress does not exist, large apparent viscosities at low shear rates inhibit an efficient sludge transport. Research indicates that the dimensionless ratio of gravity to viscous forces is an important operational parameter towards settler capacity....

The biogas process has long been a part of our biotechnical solutions for the handling of sewage sludge and waste. However, in many cases the existing process applications need to be optimized to improve the extent of biogas production as a part of the energy supply in a sustainable and viable society. Although the principles are well known, process disturbances and poor substrate utilization i...

Many theories about the rheological behaviour of melts and concentrated solutions of high molecular weight polymers are based upon the transientnetwork model, originally developed by Green and Tobolsky [l], Lodge [2], and Yamamoto [ 31. Among these theories a model proposed by Marrucci and coworkers [4,5] turns out to be rather successful [6-111. The basic equations of this model, as formulated...

The present paper offers a numerical model which can be applied for the simulation of wave height distribution on a 2-D horizontal soft mud layer. The model is based on mild slope equations and it includes combined wave refraction, diffraction, reflection and breaking. The high energy dissipation of wave height due to the presence of fluid mud layer has also been simulated. Wave height attenuat...

We present numerical simulations based on a Boltzmann kinetic model with competing interactions, aimed at characterizing the rheological properties of soft-glassy materials. The lattice kinetic model is shown to reproduce typical signatures of driven soft-glassy flows in confined geometries, such as Herschel-Bulkley rheology, shear banding and hysteresis. This lends further credit to the presen...

The objective of this study was to investigate the effect of selected biopolymers on the rheological properties of surimi. In our paper, we highlight the functional properties and rheological aspects of some starch mixtures used in surimi. However, the influence of some other ingredients, such as cryoprotectants, mannans, and hydroxylpropylmethylcellulose (HPMC), on the rheological properties o...
