The book on Biological Flow Modelling is a pioneeringexploration at the intersection of biomedical engineering andcomputational fluid dynamics. It masterfully investigates into thecomplexities of bio-fluid phenomena, from intricate airwaystructures and cardiovascular biomechanics to advanced drugdelivery systems and neurological fluid dynamics. By integratingcutting-edge simulations and clinical insights, it not onlyadvances our understanding of physiological and pathologicalprocesses but also paves the way for innovative healthcaresolutions. This comprehensive anthology showcases authors'collective expertise and vision, offering readers a profoundperspective on the dynamic interplay between fluids andbiological systems.
