computational flow mechanics (CMF) - Opis:
- In this paper, authors undertook a problem of accuracy and exactness verification of some assumptions and calculation methods that are important in the 0D modeling. The computational flow mechanics (CFM) tools and basic calculations of gas turbine cycle with heat regeneration according to Szewalski’s idea have been done. Results and conclusions for this specific problem have been presented. Gas turbine cycle with heat regeneration according to Szewalski’s idea includes regeneration as same as it is now commonly employed in steam turbine cycles. Mentioned regeneration is enabled by adding to the simple cycle devices configuration of two regenerative heat exchangers and auxiliary compressor. That modification allows to obtain working medium circulation in closed cycle inside a basic cycle. Efficiency gain is dependent on extraction pressure and extraction mass flow rate.
