Abstract

1283219 Turbine rotors J S SWEARINGEN 10 Sept 1969 [9 July 1969] 44662/69 Heading FIT The flow passages of a turbine rotor are designed such that at given points the passage walls extend substantially parallel to the resultant of the deceleration and centrifugal forces acting on a particle entrained in the working fluid at the respective given point such that the particle is not directed against the passage walls. The working fluid may be a gas containing dust or liquid droplets, a vapour which partially condenses or a liquid which vapourizes in passing through the rotor. Flow through the latter may be initially radially inwards with axial or radial discharge, initially radially inwards changing to radially outwards, or axial. In a radially inward flow rotor it may not be practical for the blade surfaces to be arranged parallel to the resultant force in regions adjacent the blade outlet edge BD. Thus the edge may be cut back or a lip 20 or ridges 23 provided on the blade together with ridges 22 on the base of the flow passage, the lips and ridges influencing the working flow so as to reduce impingement of entrained particles on the passage walls. The path of an entrained particle through a flow passage is described in detail.
