Numerical and Experimental Investigations of Steam Condensation in LP Part of a Large Power Turbine
TL;DR: In this article, the experimental investigations of steam flow with condensation in the blading system of the low-pressure (LP) part of a 360 MW turbine were presented, which provided flow visualization opportunities including localization of the front of condensation, determining distributions of pressure, temperature, velocity, and flow angle in the inter-row gaps, measurements of water droplet concentration and sizes.
Journal ArticleDOI
Absorption power cycles for low-temperature heat sources using aqueous salt solutions as working fluids
TL;DR: In this article, a theoretical exploration of the possibility of utilizing aqueous solutions of three salts (lithium bromide, lithium chloride and calcium chloride), known mainly from absorption cooling, as working fluids for APCs is presented.
Journal ArticleDOI
Wet steam energy loss and related Baumann rule in low pressure steam turbines
Vaclav Petr,Michal Kolovratnik +1 more
TL;DR: In this paper, the authors present the results of a computational analysis of the wet steam energy loss occurring in a 210MW fossil-fired and a 1000MW nuclear LP steam turbine, which operate under considerably different conditions as regards pressure level in the droplet nucleation zone, exit moisture level and droplet size spectra determined from optical extinction measurements.
Journal ArticleDOI
Impact of major leakages on characteristics of a rotary vane expander for ORC
TL;DR: In this article, a semi-empirical model with two different leakages, namely the lumped leakage area between inlet and outlet and leakage between working chambers due to delayed contact of vane and stator, is presented.
