All these turbines are single stage and high-speed. Steady state CFD simulations were carried out to assess the performance at the design and partial load as well as the axial force values.<\/p>\n<p style=\"text-align: center;\">As expected, the <strong>radial inflow turbine has exhibited the best performance<\/strong>, followed then by the centripetal reaction turbine with 4% of a relative efficiency decrease. Both impulse turbines have shown 11% less efficiency at the design point comparing to the radial inflow stage. Under the partial load, the turbines have exhibited different trends of their efficiency behaviour.<\/p>\n<p style=\"text-align: center;\"><em>In particular, with a power output reduction from 100 to 40%, the radial inflow and the centripetal turbine have lost 7% of their efficiency, while the centripetal impulse turbine 20% and the centrifugal impulse just 5%.<\/em><br \/>\nThe axial force of the radial inflow and both centripetal stages may be balanced to reach a desired value by means of the modification of the disk back seal. Instead, the centrifugal impulse stage fails to provide such a balancing, which results in high values of the axial thrust even despite an impulse nature of this stage.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>COMPARISON OF FOUR TYPES OF RADIAL TURBINES FOR A 250KW ORC POWER INSTALLATION &nbsp; Maksim Smirnov,
