Electrorheological Methods and Mechanical Properties of Blood

Popis výsledku v původním jazyce

The study presents an electrorheological method, based on the dielectric properties of dispersed systems in Couette flow, developed for identification and quantification of blood microstructural changes due to RBC aggregation-desaggregation and deformation processes at different shear rates and at different local structure of the flow field. A concurrent measurement system based on the Contraves Low Shear 30 rotational rheometer, a device with data acquisition system, software and the programming unit Rheoscan 100 were used. Three different unsteady flow conditions are simulated: rectangular, trapezium-liked and triangular regimes of changes of shear rates. The relationship between whole blood/RBC suspensions conductivity and time/shear rates was studied in parallel with the changes in the rheological behaviour under transient flow conditions. The results show the conductivity dependences on shear rate, hematocrit and temperature.
