WebDec 1, 2024 · The flow stability prediction of fore-loaded, uniformly loaded and aft-loaded compressors at each mass flow condition is carried out via the developed theoretical model and compared in Fig. 16. As shown in Fig. 16 (a), it is visible that the DF of all three compressors increases with the decrease of operating mass flow rate, which describes … In fluid dynamics, hydrodynamic stability is the field which analyses the stability and the onset of instability of fluid flows. The study of hydrodynamic stability aims to find out if a given flow is stable or unstable, and if so, how these instabilities will cause the development of turbulence. The foundations of … See more To distinguish between the different states of fluid flow one must consider how the fluid reacts to a disturbance in the initial state.
