Scientific and technical principles of designing equipment for molding products from polymeric compositions on account of their viscoelastic properties

Applied a comprehensive approach to modeling various stages of the process of extrusion - forming and cooling products to the changing rheology and melt viscoelastic effects in it, that affect the final product configuration. The methodological approach allows the numerical simulation of the formation of products from polymeric materials, design extrusion-forming equipment based viscoelastic deformation effects of products and make adjustments to the design and process parameters to achieve the form of products, more relevant given.

Scientific and technical solutions complex development for education facilities of Ministry of Education and Science of Ukraine energy management system creation

Energy management systems in different universities of Ukraine were considered. Procedures for conducting energy audits for social facilities and estimation of baseline buildings energy consumption for evaluating the implementation of energy saving measures were developed. Mathematical models of building thermal condition were created, taking into account the influence of solar and thermal radiation, thermal protection, based on European standards (simplified hourly method 5R1C) and EnergyPlus software product. Intermittent operation of heating was investigated.
