... the flow leaving the high pressure turbine to the low pressure turbine at a larger diameter without any severe loss generating separation or flow disturbances. To reduce costs and weight this turbine duct has to be as short as possible. This results in superaggressive (very high diffusion) S-shaped...

... that the flow field is two dimensional and incompressible in the ducts between blade rows although the steady-state density is permitted to change across the blade rows. The resulting stall parameter contains terms that relate to the slope of the pressure rise characteristic of the blade rows and the inertia...

... of the channel walls are also presented. The mass transfer data from the curved wall channels are compared to those from a smooth 4:1 rectangular duct with similar flow parameters. The local mass transfer data are analyzed mainly for the fully developed region, and area-averaged results are presented...

...Anant Shah; Danesh K. Tafti A ribbed square duct ( P ∕ e = 10 , e ∕ D h = 0.10 ) subjected to sand ingestion is studied using large-eddy simulations (LES). Particle sizes of 10 μ m , 50 μ m , and 100 μ m with nondimensional response times (normalized by friction velocity and hydraulic diameter...
