      <abstract xml:lang="ru">
        <p>О диффузорах имеется весьма обширная литература, и в современ­ных научно-технических источниках этому вопросу уделяется много вни­мания. Большинство этих исследований связано с разработкой кон­струкций диффузоров и посвящено определению наивыгоднейшего угла раскрытия диффузора за центробежным и осевым вентилятором, потерь давления в диффузорах, оптимальной длины диффузора и др.</p>

        <p>There is a very extensive literature on diffusers, and in modern scientific and technical sources, much attention is paid to this issue. Most of these studies are related to the development of diffuser designs and are devoted to the determination of the most favorable angle of diffuser opening behind centrifugal and axial fans, pressure losses in diffusers, optimum diffuser length, etc.</p>
