Paschenko N. Gasdinamic improvement of flowpart of the low-pressure cilinder of steam turbines high power

Object of research - the gas-dynamic processes in the flowpart of the low-pressure cylinder of steam turbines. The purpose of research - the improvement of the numerical model of three-dimensional viscous flow of steam and increasing the efficiency of gas-dynamic flowpart of the low-pressure cylinder of steam turbines high power, through the creation and use stage of highly loaded. Theoretical and practical results - developed of an interpolation-analytical method of approximation the equation of properties of water and steam for 3-D calculations. Proposed an approach to improve the gas-dynamic flowpart LPC of steam turbines. The regularities of the influence of compound lean and sweep of the stator blades at the structure of the flow and gas-dynamic characteristics of the flowpart of the LPC in a wide range of pressures in the condenser. Novelty - developed of an interpolation-analytical method of approximation the equation of properties of water and steam International Standard IAPWS-95 for calculation of three-dimensional flows of steam in the flowparts of turbomachines.. Degree of introduction - the results of the research used to "Turboatom" when selecting ways to improve existing and develop prospective LPC of steam turbines high power. Field of use is heat-power engineering.
