Scientific method of creation of ecologically clean capillary-porous systems of cooling of power equipment elements of power plants on the example of gas turbines

摘要

The novelty of the work is the development and research of a new highly accelerated capillary-porous cooling system for elements of gas turbine units, operating in the field of mass and capillary forces. Original models were created and a mechanism for the heat and mass transfer process in a capillary-porous cooling system was developed. First, equations were obtained for calculating the limiting heat fluxes and stresses for a poorly heat-conducting capillary-porous structure. Experimental setups and research methods using various porous structures have been developed. The experimental data for the vaporization processes in the studied porous system with boiling in a larger volume, thin-film evaporators and heat pipes is generalized. Newly developed systems make it possible to achieve savings in fuel, air, water and heat, whilst increasing the reliability of cooling and fire safety of the equipment concerned, as well as to obtain great economic and social effects in the field of ecology and health and safety.
