Провести оптимизацию имплантируемого осевого насоса для повышения гидравлической эффективности и снижения гемолиза крови. Материалы и методы. С использованием методов вычислительной гидродинамики проведен расчет и оптимизация основных геометрических параметров геометрии рабочего колеса (угол лопаток на входе насоса, длина лопатки и коэффициент угла закрутки). Расчеты проводились для оптимального режима работы насоса при скорости вращения 8000 об/мин. Результаты. В результате проведенных исследований были определены параметры рабочего колеса, которые позволили повысить КПД насоса в среднем на 7,5% (в зависимости от режима работы насоса) и перепад давления в среднем на 8%. Значение сдвигового напряжения в проточной области, полученное в результате расчетов, не превышало 147 Па, что допустимо с точки зрения гемолиза крови.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To optimize implantable axial pump to increase hydraulic efficiency and reduce blood hemolysis. Materials and methods. In this article the basic geometric parameters of impeller’s geometry (the blade’s angle, the blade’s length and the twist angle’s ratio) were investigated and optimized using methods of computer hydrodynamics. The calculations were carried out for the optimum operation of the pump at the speed of 8000 rpm. Results. The main parameters of impeller’s geometric were determined which made it possible to increase efficiency of the pump by an average of 7.5% (depending on the pump operation mode) and pressure drop of 8% on average. The value of shear stress in the flow region obtained as a result of the calculations did not exceed 147 Pa admissible from the point of view of blood hemolysis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>механическая поддержка кровообращения</kwd><kwd>осевой насос</kwd><kwd>трехмерная математическая модель</kwd><kwd>расходно-напорные характеристики</kwd><kwd>КПД</kwd><kwd>рабочее колесо</kwd><kwd>сдвиговое напряжение</kwd><kwd>гемолиз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mechanical support of blood circulation</kwd><kwd>axial pump</kwd><kwd>3D mathematical model</kwd><kwd>flow-pressure characteristics</kwd><kwd>efficiency</kwd><kwd>impeller</kwd><kwd>shear stress</kwd><kwd>hemolysis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Versteeg HK, Malalasekera W.
