The main aim of the Magnetic Blood project is to provide to the scientific community with a pioneering guideline able to predict the viscoelasticity of blood under the application of magnetic fields in shear and/or uniaxial extensional flows.
Understanding the rheological properties and flow dynamics of whole human blood is of great importance for the early detection, diagnosis, and therapy of circulatory disorders as well as for the development of cardiovascular devices and prosthesis, such as blood pumps, heart valves or stents. Some diseases, such as cardiovascular disorders, myocardial infarction, arterial hypertension, diabetes mellitus, cholesterol and triglyceride levels and sickle cell anemia could be monitored by a routine screening of hemorheological measurements. The flow of blood in physiological conditions typically involves large deformations, large deformation rates and periodic forcing with large amplitude and therefore characterization of blood under large amplitude oscillatory shear flow (LAOS) is of great importance, also under conditions of extensional flow.
Nevertheless, it is common the use of external magnetic fields in the diagnosis and in the treatment of many diseases. The use of variable magnetic fields in medicine covers areas as orthopedics, rheumatology, internal medicine, neurology, or dentistry. A novel and fully rheological characterization of whole blood under the action of external fields in shear and extensional flows is, therefore, fundamental to provide deeper insight into new treatment therapies.
The aim is to provide for the very first time a complete understanding of the microstructural changes of whole human blood as magnetic fields are applied. Consequently, the viscoelasticity will undergo a clear dependence of the external forces apart for the well-known dependence of RBC concentration or temperature.
The objective of this work is to characterize the onset of laterally asymmetric flow of viscoelastic solutions around a confined microfluidic cylinder, which was encountered in a recent study [Rodrigues
