Development of technology and equipment for profiling of corrugated and ribbed tubes and creation of high-performance heat exchangers

The work is aimed at creation of high-efficiency heat regenerators of gas turbine units (GTU) of the gas transportation system of Ukraine. It is proposed to use highly effective heat exchange surfaces from the tubes of the spiral corrugated profile with high heat and aerodynamic characteristics for heat regenerators GTU, which will ensure a reduction of mass-dimensions by 30- 40% in comparison with heat exchangers made of smooth round tubes and an increase in the KPD GTU from 18-25% to 38-41%.
