Kuznetsova S. Analysis and evaluation of circulation contours efficiency of ship contact gas-steam turbine plants

The object is circulating contour of ship contact gas-steam turbine plants; the aims to evaluation of circulating contours efficiency; the methods are mathematical and experi- mental simulation elements of circulating contours and in circulating contours; the new approach lies in processes of water recovering is considered as consequent processes of condensation and separation from gas-steam mixture by meant of the intermediate water heat cooler; water recovering is modeled by the processes of evaporation cooling,contact condensation and separation of water droplets; results of water recovering modelling are parameters of efficiency on water return on heat transfer and used potential. Parameters of efficiency are function of determined and casual values when the ship contact gas- steam turbine plant is used on ship, sea or land objects. Determined values are parame- ters constructive of contact condenser and water cooler. Casual values are parameters of plant power, temperature and humidityof atmospheric air, sea water temperature, region of navigation.Criteriation of efficiency parameter is differential function of parameter distribution; all this thesis has been developed by shipbuilding plants; the field is ship heat power engineering.
