ABSTRACT
Computational modeling and simulation have brought several improvements in engineering and their processes. Engineering area advances in the past decades are related to the simulation capability improvements. On bioengineering, especially on ventricular assist devices (VAD) device and development, they are not different from general engineering designs. Several approaches commonly applied on traditional computational fluid dynamics (CFD) are being applied to simulate blood flow, aiming to reach better understanding and improvements in artificial hearts. In this area, computational hemodynamic and computational aerodynamic may reach outstanding results even in the face of difficulties and complexities of simulating blood flow inside flux machines. This chapter brings important and crucial aspects of computational hemodynamic, including aspects of mesh, solver methods, best practices, rheology, software and their overall comparison, new approaches, and future advances. Therefore, it explores crucial content to any who intend to study and develop artificial hearts.
