Experimental method for the study of blood and RBC suspension conductivity under flow
Result description
The study presents an electrorheological method developed for quantifica- tion of blood microstructural changes due to RBC aggregation-disaggregation and deformation processes at different shear rates and at different local struc- ture 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-like and trian- gular regimes of changes of shear rates. The time variation of blood and RBC suspension conductivity at these unsteady flow conditions under electric field of 2 kHz are presented. The results show that the blood and RBC suspension conductivity is strongly dependent on shear rate, haematocrit, temperature and on the considered blood flow regimes.
