the motivation for this work is to propose a first thorough review of dough rheological models used in numerical applications. although many models have been developed to describe dough rheological characteristics, few of them are employed by researchers in numerical applications. this article reviews them in detail and attempts to provide new insight into the use of dough rheological models.

The primary cement job is a critical step in successful well completion. To achieve effective cementing job, complete mud removal from the annular is recommended. Spacer and flushers are used widely to achieve this goal. This study is about weighted cement spacer systems containing a surfactant package, weighting agent and rheological modifiers. Weighted spacer systems are utilized when a high ...

The most important experimental methods of studying the mechanical properties cells, as well common rheological models, among which discrete models micro/nanostructure cell and continuous that allow calculating modulus elasticity viscosity in normal pathological conditions are discussed. A review is given with an indication their features differences. new continuum model a multi-layer shell fil...

Rheological object, such as various food products and biological tissues, has both elastic and plastic properties. Modeling of rheological object has not been studied frequently comparing with the modeling of elastic one. Our previously developed FE models of rheological objects were based on triangular or tetrahedra finite elements. In this paper, the FE model of rheological object formulated ...

The cytoskeleton is a complex structure within the cellular corpus that is responsible for the main structural properties and motilities of cells. A wide range of models have been utilized to understand cytoskeletal rheology and mechanics (see e.g. [Mofrad, M., Kamm, R., 2006. Cytoskeletal Mechanics: Models and Measurements. Cambridge University Press, Cambridge]). From this large collection of...

Multiple interacting mechanisms control the formation and dissolution of clots to maintain blood in a state of delicate balance. In addition to a myriad of biochemical reactions, rheological factors also play a crucial role in modulating the response of blood to external stimuli. To date, a comprehensive model for clot formation and dissolution, that takes into account the biochemical, medical ...

Modeling of magneto-rheological dampers to be used in semi-active control of civil engineering structures is addressed. The behavior of this kind of dampers is modeled through a first order Lugre dynamic friction model whose structure is analytically simpler than other dynamic friction models used in the literature. With this structure real-time parametric identification of the magneto-rheologi...

Rheological data on a food together with data on its composition and structure or microstructure should lead to understanding the interrelationships between them. A number of foods are dispersions of solids in liquids, liquids in liquids, or gas in liquids. The dispersed particles may be colloidal in nature with dimensions < 10 mum, or larger noncolloidal particles (> 10 mum). For both colloida...
