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%.

Development equalincreased heat transfer surfaces for gas turbine regenerators of gas transport systems and research their heat-aerodynamics characteristics

Gas turbine unit ( GTU) is the dominant type of drive gas transportation system of Ukraine. However, most of them morally and physically obsolete, leading to a waste of gas for its own needs, which in 2010 amounted to 4.9 billion m3. To improve gas turbine is to use the least expensive stoves (regenerator) for utilization of heat in the turbine exhaust gases at the same time regenerators at current levels of use are bulky often have low operational reliability.
