Cyclic Aero Engine Motivated Cavity Flows,atic diagram showing a cross-sectional view through a high-pressure compressor drum is shown in .. Some of the central axial throughflow enters the relatively warm cavities formed between the adjacent discs and a parasitic temperature rise Δ. occurs. Knowledge of the heat transfer in these cavities is important for designers.

Overview of Elementary Temporal Discretizations,rgy conservation and also the transport of passive scalars and certain turbulence parameters. To a lesser extent, CFD predictions can involve the solution of Lagrangian particle transport equations. For unsteady flows (and also the particle transport equations) the temporal discretization process ne

Temporal and Spatial Discretization Relationships,eadier. The reduction of unsteadiness, may in some situations involve using several coordinate systems. This practice is common in turbomacinery design where sets of adjacent stationary and rotating blades are modelled in stationary and rotating coordinate system, respectively. Use of this approach,

Cyclic Complex System Flow,n hollow block like components defined as regions 1, 2 and 3. Regions 1 and 2 have fans attached to them. A key feature of this chapter is that the predictive behaviour of a wide range of turbulence models is compared when computing a complex system cyclic flow. Some of the adaptive time-step approa

Transient Complex System Flow, this, the wall has tangential rotational movement. This produces a relatively simple shear flow with wall aligned streamlines. However, frequently transient flows involve ., where a suddenly released fluid interacts with downstream mechanical structures. The resulting flow structures can then be co
