Experimental Study of an Improved Design for the Exhaust Steam Passage of a Low-pressure Turbine Cylinder

To enhance the work efficiency as well as the operation reliability and safety of a steam turbine unit, an experimental study was conducted of the various improved design schemes of a complicated exhaust steam passage for a low pressure naval steam turbine fitted with an astern unit. The results of the experimental study indicate that the rational layout of a diffusion section and the addition of a flow guide device can be conducive to a reduction of exhaust steam loss and a lessening in flow field non uniformity.
