Red blood cells (RBCs) can aggregate and disassociate reversibly under normal physiological conditions. Cardiovascular diseases like hypercholesterolemia and diabetes have been associated with increased RBC aggregation. Fibrinogen is the main cause of this aggregation. The normal range for human fibrinogen levels is 1.8 - 4 mg/ml. Diabetes can cause stable aggregates to form, leading to vessel blockages. This study aims to investigate the influence of adhesion between red blood cells and between RBCs and vessel walls on their behaviour in blood vessel networks. This encompasses RBC and plasma distribution, blood flow rate, and RBC lingering. Studying adhesion's impact on RBC behaviour is crucial for comprehending the intricate dynamics of blood flow in microvessels. We employ the lattice Boltzmann method in 2D to simulate RBCs behaviour with adhesion in a complex vascular network.
