In this paper, a new rheological model for the flow of phosphate-water suspensions is proposed. The model’s ability to replicate characteristics under different shear rate conditions evaluated using rheometric tests, and it found be in good agreement with experimental data. A comprehensive methodology obtaining parameters presented. proposed then incorporated into OpenFoam numerical code. resul...

Electroand magnetorheological uids are smart, synthetic uids changing their viscosity from liquid to semi-solid state within milliseconds if a su ciently strong electric or magnetic eld is applied. When used in suitable devices, they o er the innovative potential of very fast, adaptively controllable interfaces between mechanical devices and electronic control units. This paper gives an overvie...

Design of polymer properties, especially the relation between tensile and dynamic moduli in terms of chain conformational statistics was considered. Data on new elastomer blends with gradient properties enabling mixing on the molecular level were analysed in parallel to classical commodity materials. A new model describing the rheological behaviour of immobilized biopolymers was developed and t...

Using confocal microscopy, we study the flow of a model soft glassy material: a concentrated emulsion. We demonstrate the micro-macro link between in situ measured movements of droplets during the flow and the macroscopic rheological response of a concentrated emulsion, in the form of scaling relationships connecting the rheological "fluidity" with local standard deviation of the strain-rate te...

Introduction MR-Elastography (MRE) enables additional characterization of pathologies by providing new physical parameters, for instance the complex shear modulus G*(ω)=Gd(ω)+Gl(ω) at a single frequency [1,2]. However, interpretation of G*(ω) in terms of elastic and viscose properties necessitates the knowledge about the underlying rheological model. Tissue is a material with a hierarchical org...

AbatraetDynamic behavior of gas emboti in a quiescent liquid having the rheological properties of human or animal blood subject to pressure variations is studied. Consideration is given to step and sinusoidal changes in the system pressure. It is disclosed that in the study of dynamic behavior of gas emboli, a Newtonian model may be used to approximate the rheological behavior of human or anima...

Semi-active control systems have been widely studied over the last 20 years. The range of applications includes automotive suspensions, seismic vibration mitigation, large bridges vibration control, knee prosthesis, among others. Semi-active actuators have a complex dynamics, and interaction between actuator and plant cannot be ignored in control design. This is specially true for magneto-rheol...
