【 摘 要 】

The most competitive left ventricular assist devices (LVAD) in the world were identified in this article. 3D models of two samples were constructed for pumping blood based on existing pumps. The models were imported into the software package, where the flow of blood through these models was modeled. For this, a computational grid was constructed. According to the results of calculations, the main characteristics of the samples were obtained, as well as pictures of the distribution of velocities and pressures in the flow part. The calculation used a number of basic hydraulic equations that form a mathematical model.
