- Abstract:
-
Turbine flexible operations with faster startups/shutdowns are required to accommodate emerging renewable power generations. A major challenge in transient thermal design and analysis is the time scale disparity. For natural cooling, the physical process is typically in hours, but on the other hand, the time step sizes typically usable tend to be very small (sub-seconds) due to the numerical stability requirement for natural convection as often observed. An issue of interest is what time step...
