On the rheological modeling of blood flow around a clot
نویسنده
چکیده
The aim of this paper is to present a possible approach to modeling the influence of clot formation on blood flow in a vessel. The modeling framework adopted in this work is based on a modification of the fluid viscosity within the clot area. A non-Newtonian blood flow model in a three-dimensional straight vessel is considered and its numerical solution is obtained using a finite-volume method. Finally, a qualitative analysis of the results is presented together with some guidelines for future coupling with a biochemical model. Key–Words: Non-Newtonian fluid, blood flow, coagulation, clot, finite-volume method.

Development of a rheological model for polymeric fluids based on FENE model
Rheological models for polymer solutions and melts based on the finitely extensible non-linear elastic (FENE) dumbbell theory are reviewed in this study. The FENE-P model that is a well-known Peterlin approximation of the FENE model, indicates noticeable deviation from original FENE predictions and also experimental results, especially in the transient flow. In addition, both FENE and FENE-P mo...
متن کاملModeling the Time-Dependent Rheological Properties of Pistachio Butter
Pistachio butter (semi solid paste), which is made from roasted pistachio kernels, is an appropriate alternative to work on because of its high nutritional and economical values. In this study, timedependent flow properties of pistachio butter were determined at two different temperatures (25˚C and 45˚C) for five different formulations (with different levels of emulsifying agents). Forward a...

The aim of this research was to assess the effect of fat type and concentration as well as the continuous phase viscosity on the rheological properties of an oil-in-water (O/W) emulsion. Thus, sunflower oil and tallow fat were used as the dispersed phase of the emulsion both at 10 and 50% (w/v) and CMC solutions (at 0.1, 0.3 and 0.5% w/v) were acted as the continuous phase. CMC solutions and em...
متن کاملMathematical modelling of Sisko fluid flow through a stenosed artery
In the present study, the nonlinear model of non-Newtonian blood flow in cosine-shape stenosed elastic artery is numerically examined. The model is carried out for axisymmetric, two-dimensional and fully developed blood flow. The vessel wall is assumed to be have time-dependent radius that is important factor for study of blood flow. The cosine-shape stenosis convert to rigid artery by using a ...
متن کاملA Study on Ratio of Loss to Storage Modulus for the Blood Clot
In this study the rheology of blood clot is measured with the help of rotational rheometer. Several shear strain (0.5, 1 and 2%) are applied with two frequencies (5 and 10 Hz) from the incipient time of clot formation and the response of the sample is measured with the form of shear stress and the phase lag which is interpreted with storage and loss moduli. In this study the ratio of loss to st...
