Paper No: GT2021-59936
...Abstract Abstract Uncertainty around the design and control of the supercritical CO2 power cycle must be reduced before this technology can be implemented for large-scale grid support. To better understand the day-to-day performance of an sCO 2 cycle, off-design performance calculations must...

..., one for charging and the other one for discharging. Although PTES thermodynamical behavior is well understood, the interaction between the components is rarely investigated. This study investigates the impact of packed-bed behavior on turbomachines operating conditions. In this way, PTES off-design...

... is to introduce a newly developed tool for the simulation of design and off-design conditions of gas turbine-based cogeneration systems, where heat is recovered through a Heat Recovery Steam Generator. The tool is meant to be driven by a small amount of inputs, making it possible to define sharp strategies...

... optimization processes. To demonstrate feasibility of the present method, a 10-stage compressor was optimized to maximize its total pressure ratio of operating point in off-design conditions. The variable geometries that were studied in this paper are: (1) VIGV; (2) VIGV and first row variable stator; (3) VIGV...
