The assumed rheological behavior of blood influences the hemodynamic characteristics numerical flow simulations. Until now, alternative specifications have been utilized, with uncertain implications for results obtained. This work aims to group sixteen models in homogeneous clusters, by exploiting data generated from simulations on an idealized symmetrical arterial bifurcation. Blood is be puls...

rheological properties of chocolate are important in manufacturing process for obtaining high-quality products with well-defined texture and are directly influenced by composition and their refining time. soy protein benefits from nutritional and functional properties to be used in different foods. effects of different replacement levels of skim milk powder by soy flour, (from 0 to 100%) and ba...

A review of flow and texture modeling of liquid crystalline materials with emphasis on carbonaceous mesophases is presented. Two models of nematodynamics are presented and discussed in terms of their ability to resolve time and length scales likely to arise in typical rheological and processing flows. Defect physics and rheophysics are integrated with nematodynamics and specific mechanisms of d...

Stress–strain response under constant and variable strain-rate is studied for selected models of inelastic behavior. The derived closed-form solutions for uniaxial loading enable simple evaluation of the strain-rate effects on the material response. The effect of an abrupt change of strain-rate is also examined. Non-Newtonian viscosity which decreases with an increasing strain-rate is incorpora...

A physical modeling of rheological objects is presented. Objects showing rheological nature involve foods and biological tissues yet no systematic approach to build their virtual objects is not established. In this article, we will construct 2D/3D virtual rheological objects.

In this paper the drag-out problem for shear-thinning liquids at variable inclination angles is considered. For this free boundary problem dimension-reduced lubrication equations are derived for the most commonly used viscosity models, namely, the power-law, Ellis, and Carreau model. For the resulting lubrication models a system of ordinary differential equations governing the steady state solu...

This paper presents a methodology for identifying variable-structure models of magneto-rheological dampers (MRDs) that are structurally simple, easy to estimate and well suited for model-based control. Linear-in-the-parameters NARX models are adopted, and an identification method is developed based on the minimisation of the simulation error. Both the model structure and the parameters are sele...
