Alyokhina S. Modeling of thermal processes in energy equipment of HES and AES by the solution of the conjugate problems of heat exchange

Object - thermal and hydrodynamical processes which pass elements of the power equipment; maintenance of reliability and safety of work of the power equipment on the basis of research of its thermal condition; methods - mathematical modelling with use of numerical methods of the decision of the conjugate heat transfer problems; results - the level of change of heat transfer coefficient on surfaces thermal expansion grooves is determined at non-stationary modes of heating-up a rotor; it is expanded a range of use criterion dependences for definition of heat transfer coefficient on a surface of a rotor; the information system of monitoring of power units loading is developed and introduced; the thermal condition of containers of storage with spent nuclear fuel on a platform of storage is determined; novelty - temperature fields, vector fields of velocitys, heat transfer coefficient in a zone trailer and diaphragm condensation are received; The technique of the control of loading of power units is developed; temperature fields vector fields of velocitys of the ventilated container of storage with spent nuclear fuel, and also group of containers on a platform are received; it is introduced - distribution of heat transfer coefficient and new forms thermal expansion grooves on KhCDO "Energoprogress", information system of monitoring of loading of power units on the Kharkov TPS-5, the data about a thermal condition of containers of storage of the fulfilled nuclear fuel on KhI "Energoproekt"; Field of use is industrial heat-and-power engineering.
