This note is concerned with the essential part of Finite Element Methods (FEM) approximation error analysis for quasi-Newtonian modelling thixo-viscoplastic (TVP) flow problems. The developed FEM settings thixotropic generalized Navier-Stokes equations based on a constrained monotonicity and continuity coupled system, which cornerstone an efficient monolithic Newton-multigrid solver. manifested...

Functionalized biomass waste sources of cellulose have drawn attention due to their high availability and sustainability properties. In this work we characterize the structural flow properties high-pressure homogenized citrus fiber dispersions, employing SAXS, rheology rheo-MRI techniques. The treatment disrupts microfibrillar network within fibers, but leaves individual microfibrils intact. Un...

Materials with mechnoresponses are a new discipline in organic soft matter synthesis. One mechanoresponse, thixotropy, is the tendency of a material to become less viscous upon the addition of mechanical stress such as shaking. Separately in other gels, a visible color change during the gel-to-solution transition has been observed. While gels with either thixotropic or color-change qualities ha...

Pharmaceutical, cosmetic and personal care products are mainly based on emulsions their rheological behavior can be a critical factor for successful use. Thus, analysis is promising tool, since the stability, sensory aspects processing parameters assessed. This work presents analyses of 39 samples use data obtained in tool artificial neural networks (ANN), order to predict performance emulsions...

A new brittle-elastoviscoplastic (BEVP) fluid model is presented in this paper. This relatively simple to use, as it contains few material parameters and a fixed-point algorithm effective for solving the coupled system of equations. The combines some existing fundamental features such elasticity, plasticity brittle damage. combination them based on thermodynamics that ensures positivity dissipa...

Silver powders were prepared by a chemical reduction method. Effects of different surfactants during this preparation process examined. Using these silver powders, pastes for low temperature co-fired ceramics (LTCC) applications. Another batch added into the paste and evaluated. Moreover, various organic thixotropic agents used to modify thixotropy behavior paste. It was found that PVP (Polyvin...

The distinctive properties of bentonite such as hydration, swelling, water absorption, ion adsorption, high viscosity, and thixotropy make it a valuable material for many applications in geotechnical engineering hydraulic barriers, drilling slurry, landfill liners. Many additives cement, hay fiber, polymer have been used to enhance the performance which are proved respected research. This study...

Abstract Online control of industrial processes by lean principle increases productivity and yields higher product quality. Polysaccharides are dissolved in liquids, such as water, many products, like paints, cosmetics culinary products. In these it is important to viscosity or create thixotropy yield stress for functionality. Electromagnetic field electrical conductivity techniques were applie...
